Check Website Hosting Ip
A web hosting service is a kind of internet hosting service that permits individuals and companies to make their website accessible via the world wide web. Web hosts are companies that offer space on a server owned or leased for use by customers, as well as providing internet connectivity, usually in a data center. Web hosts can also supply data center space and connectivity to the internet for other servers located in their data center, called colocation, also known as Housing in Latin America or France.
History
Up till 1991, the internet was restricted to use only "...for research and education in the sciences and engineering..." and was used for email, telnet, FTP and USENET traffic, but only a small number of web pages. The world wide web protocols had only just been established and not until the end of 1993 would there be a graphical web site browser for Mac or Windows computers. Even after there was some opening up of internet access, the situation was confused until 1995.
To host a web site on the internet, an individual or organization would need their own computer system or server. As not all companies had the budget or capability to achieve this, website hosting services started to supply services to host users' websites on their own servers, without the customer needing to build the necessary infrastructure required to operate the website. The owners of the sites, also referred to as webmasters, would be able to construct a site that would be hosted on the web hosting service's server and published to the internet by the web hosting service.
As the number of users on the internet increased, the demand for organizations, both large and tiny, to have an online presence grew. By 1995, organizations such as GeoCities, Angelfire and Tripod were providing free hosting.
Classification
Smaller Hosting Services
The most basic is aweb page and small-scale file hosting, where files can be uploaded via File Transfer Protocol (FTP) or a web interface. The files are generally delivered to the web "as is" or with very little processing. Quite a few internet service providers (ISPs) supply this service free to subscribers. People and organizations may also acquire web page hosting from alternative service providers.
Free web hosting service is supplied by different companies with limited services, generally supported by advertisements, and at times limited when compared to paid hosting.
Single page hosting is at times sufficient for personal web pages. Personal web site hosting is typically free, advertisement-sponsored, or inexpensive. Business web site hosting often has a greater expense depending upon the size and type of the site.
Larger Hosting Services
Many large organizations that are not internet service providers need to be constantly connected to the web so they can send email, files, etc. to other sites. The organization may use the computer as a website host to supply details of their goods and services and facilities for website orders.
A complex site will have a more inclusive package that offers database support and application development platforms (e.g. ASP.NET, ColdFusion, Java EE, Perl/Plack, PHP or Ruby on Rails). These programs allow customers to create or install scripts for applications like forums and content management. Also, Secure Sockets Layer (SSL) is typically used for websites that wish to keep the data transmitted more secure.
Types of Hosting
Internet hosting services can manage web servers. The scope of web hosting services varies quite a bit.
Shared Web Hosting Service
One's website is found on the same server as many other sites, ranging from a few websites to hundreds of websites. Typically, all domains may share a common pool of server resources, such as RAM and the CPU. The features available with this type of service can be relatively simple and not flexible in terms of software and updates. Resellers often provide shared web hosting and website organizations sometimes have reseller accounts to offer hosting for clients.
Reseller Web Hosting
Reseller web hosting allows clients to take on the role of website hosts themselves. Resellers may function, for individual domains, under any combination of these types of hosting, depending on who they are affiliated with as a reseller. Resellers' accounts may differentiate a great deal in size: they may have their own virtual dedicated server to a colocated server. Many resellers offer a nearly identical service to their provider's shared hosting plan and offer the tech support themselves.
Virtual Dedicated Server
Also known as a Virtual Private Server (VPS), it divides server resources into virtual servers, where resources can be handed out in a way that does not directly reflect the shared hardware. VPS will at times be allocated resources based on a one server to many VPSs relationship, however, virtualization might be chosen for varying reasons, including the option to relocate a VPS container from one server to another. Users may have root access to their own virtual space. Users are often responsible for fixing and maintaining the server (unmanaged server) or the VPS provider may provide server admin tasks for the customer (managed server).
Dedicated Hosting Service
The customer gets his or her own web server and has full control over it (user has root access for Linux/administrator access for Windows); but, the customer generally doesn't own the server. One type of dedicated hosting is self-managed or unmanaged. This is typically the least expensive for dedicated plans. The client has full admin access to the server, which means the client is responsible for the security and maintenance of their own dedicated server.
Managed Hosting Service
The customer gets their own website server but is not allowed full control over the server (the user is denied root access for Linux/administrator access for Windows); however, they can manage their data via FTP or other remote management software. The user is not allowed complete control so that the provider can guarantee the quality of service by not granting the customer to modify the server or possibly create configuration issues. The customer sometimes does not own the server. The server is leased to the user.
Colocation Website Hosting Service
Similar to the dedicated website hosting service, but the customer owns the colocation server; the hosting organization offers physical space that the computer takes up and takes care of the computer. This is the strongest and expensive type of web hosting service. In most cases, the colocation provider may supply little to no assistance directly for their customer's machine, providing only the electrical, internet access, and storage facilities for the computer. In most cases for colocation, the user would have his own administrator go to the data center on-site to do any hardware upgrades or changes. Formerly, many colocation providers would accept any computer configuration for hosting, even ones housed in desktop-style minitower cases, but most hosting organizations now demand rack mount enclosures and standard system configurations.
Cloud Hosting
This is a new type of hosting platform that allows users strong, scalable and reliable hosting based on clustered load-balanced servers and utility billing. A cloud-hosted website may be more stable than alternatives as other servers in the cloud can compensate when a single piece of hardware breaks. Furthermore, local power disruptions or even natural disasters are less problematic for cloud hosted sites, as cloud hosting is decentralized. Cloud hosting also permits providers to invoice users only for resources used by the client, rather than a flat fee for the amount the customer assumes they might consume, or a fixed rate upfront hardware investment. Alternatively, the lack of centralization may provide customers less control on where their information is located, which could be problematic for users with data security or privacy concerns.
Clustered Hosting
Having a group of servers host the same content for better resource utilization. Clustered servers are a good solution for high-availability dedicated hosting, or having a scalable website hosting system. A cluster may separate website serving from database hosting capability. (Generally website hosts use clustered hosting for their shared hosting plans, as there are a lot of benefits to the mass managing of clients).
Grid Hosting
This form of distributed hosting is when a server cluster performs like a grid and is made of multiple nodes.
Home Server
Typically, a single computer placed in a private home can be used to host one or a few web sites from a typically consumer-grade broadband connection. These can be purpose-built servers or more commonly older PCs. Some ISPs actively work to block residential servers by blocking incoming requests to TCP port 80 of the user's connection and by refusing to offer static IP addresses. A wonderful way to get a reliable DNS hostname is by obtaining an account with a dynamic DNS service. A dynamic DNS service will automatically change the IP address that a URL directs to when the IP address changes.
Some specific types of hosting supplied by website host service providers:
- File hosting service: hosts files, not web pages
- Image hosting service
- Video hosting service
- Blog hosting service
- Paste bin
- Shopping cart software
- Email hosting service
Host Management
The host could also supply an interface or control panel for managing the web server and installing scripts, as well as other modules and service applications like email. A website server that does not use a control panel for managing the hosting account, is often referred to as a "headless" server. Some hosts specialize in certain software or services (e.g. e-commerce, blogs, etc.).
Reliability and Uptime
The availability of a website is measured by the percentage of a year in which the site is publicly available and reachable via the internet. This is different from measuring the uptime of a system. Uptime refers to the system itself being online. Uptime does not take into account being able to reach it such as during network outage. A hosting provider's Service Level Agreement (SLA) may include a certain amount of scheduled downtime per year in order to perform maintenance on the systems. The scheduled downtime is sometimes excluded from the SLA timeframe and needs to be subtracted from the Total Time when availability is calculated. Depending on the wording of an SLA, if the availability of a computer drops below that in the signed SLA, a hosting provider often will offer a partial refund for time lost. How downtime is calculated is different from provider to provider, therefore reading the SLA is important. Not all providers publicly display uptime statistics. Quite a few hosting providers will guarantee at least 99.9% uptime which will provide for 43 minutes of downtime each month, or 8 hours and 45 minutes of downtime every year.
Obtaining Hosting
Website hosting is sometimes supplied as part of a general internet access plan from internet service providers. There are also a number of free and paid providers offering web hosting.
A client needs to evaluate the requirements of the application to choose what kind of hosting to use. Such considerations include database server software, scripting software, and operating system. A number of hosting providers provide Linux-based website hosting which provides a wide range of various software. A usual configuration for a Linux server is the LAMP platform: Linux, Apache, MySQL, and PHP/Perl/Python. The website hosting user may want to obtain other services, such as email for their business domain, databases or multimedia services. A customer might also prefer Windows as the hosting platform. The client still can choose from Perl, PHP, Python, and Ruby, but the customer may also use ASP.NET or ASP Classic. Website hosting packages sometimes include a website content management system, so the end-user doesn't have to worry about the more technical parts.
Security
Since website hosting services host websites belonging to their clients, online security is a vital topic. When a client agrees to use a web hosting service, they are passing on control of the security of their site to the service provider that is hosting the website. The degree of security that a web hosting service offers is quite important to a possible client and can be a major consideration when deciding which supplier a client may choose.
Website hosting computers can be attacked by malicious users in different ways, including uploading malware or malicious code onto a hosted website. These attacks {may|might| be done for different reasons, such as stealing credit card info, launching a Distributed Denial of Service Attack (DDoS) or spamming.
