An IP address is an identification number assigned to a device (e.g. a computer or a printer) connected to the Internet can be a PC, a laptop, web host server, and a mobile device and has a unique IP address.IP stands for Internet Protocol, the most popular open-system protocol used to communicate across any sets of interconnected networks including Local Area Networks (LAN) or Wide Area Networks (WAN). It is a collection of 4 number string, begins at 0 and ends up to 255. An IP address consists of 4 sets of 8-bit numbers (octet) with a total of 32-bits, each separated by a dot (.). For each of the 4 sets of octets in an IP address, the maximum possible value is 255 (representing an octet containing all ones). It will look like:-
Above code helps to identify machine currently using. After identification, data sent on the Internet means large a number of websites can be accessed by user offering by the Internet.
Shared IP address
Web host uses a server to host website is a single machine with single IP address. At given time, a server can host thousands of websites in shared web hosting. Single IP address allocated to host’s server recognizes all these websites.
hared IP is used by more than one virtual hosts. This approach is known as name-based Virtual Host Support, as opposed to the traditional IP-based Virtual Host approach. The traditional approach is hard to implement on some machines, so Shared IP is used to avoid assigning a dedicated IP address to every virtual host.
The benefits of using the new name-based virtual host support are:
- virtually unlimited number of servers;
- ease of configuration and use;
- No additional hardware or software requirements.
The main disadvantage is that the client must support this part of the protocol. Also, which is critical for Control Panel, shared IP does not allow to create FTP Virtual Hosts.
Dedicated IP address
If anyone has own server and one website only on that server then IP address is dedicated by default. On a particular server, more than one site resides usually. The dedicated IP address is an IP address which is allocated to a server for the single website instead of the machine itself.
Dedicated IP is a paid service. You need a Dedicated IP to create Virtual FTP. This service uses SSL on your web server. Switching back from Dedicated IP to Shared IP will remove any of your FTP and SSL resources.
By default, every domain has a Shared IP. Shared IP is free. You can change the type of IP at any time as you work with the system. To change the type of the IP, click the Change to Shared/Dedicated IP link in the Edit Domain page.
For what Dedicated IP addresses
Dedicated IP addresses are mostly used on larger e-commerce websites for secure encryption. It means sensitive data is stored such as credit card numbers. According to many people, it is more advantageous that a website has its own IP address regarding SEO rather than hundreds of website sharing same IP address.
Is it beneficial having own IP address of website as concerned with SEO?
Speed : In some cases, dedicated IP address can be beneficial for SEO. To a single server, thousands of shared hosting is added. It means websites will have some sharing resources with that sites which will be more successful than its own. Resultant, those sites might slow down the website. As a site is slower, Google's ranking further goes down. Unique IP address is added to a website doesn't mean fast loading but it will be migrated to Dedicated Server having Dedicated IP address. Therefore, instead of adding Dedicated IP address of a website on a shared server, a site will be moved to website hosting machine. It gives dedicated IP address to a website and pays dividends. Website of a client will be more reliable, secure and faster.
SSL: Google has started to give preferences to that website which have added SSL 2048-bit key certificate. Website URL changes from HTTP to HTTPS. Unique IP addresses are utilized by SSL sites. However, Google has advised some changes in terms of SSL, affecting search less than 1%. It is still authorized SEO benefit. Encryption of website visits is done by SEO. A website that store sensitive information utilizes SSL. A website will be more visible by SSL through public networks and websites can operate fast. It means website might be hit by more visitors and operates more quickly in concern with Google causing higher placements.
Malware: Shared hosting is utilized by a server which can port thousands of websites and some sites containing malware. Some observed that user IP address is shared by those sites, so that website will be recognized as ‘bad neighborhood' residence and as concerned with search ranking it will be penalized. Dedicated IP address will be more beneficial in these cases and again move a website to a reliable server and web host.
