IP Address Checker

Tool Details and User Instructions

IP address (Internet Protocol Address) is an address of a computer or a device Using TCP/IP on a network. The numbers “70.72.170.245” are the example of an IP address. There are three main classes (groups) of an IP: A Class, B Class, C Class.

Enjoy our free IP checker tool to extract C class of an IP. You may put valid domain name, for example, “visiospark.com” instead of an IP.

Note: Only 50 IP’s allowed

C-Class is the particular sets of large networks where a few computers are attached.  First three octets are used by C Class to identify a network, possibly 20,080,800 which means, 254 computers supported by each of them.

Why there is so much talk about C Class IPs?

Mostly “C Class IPs” are used by SEO hosting providers to assign to the websites so that they can link to each other without getting any search engine penalty. C Class IP may signal the search engines (we are not sure) that the same person owns all the linking websites.

There are two schools of thought on SEO hosting::

1. According to the one side, using C Class IPs through SEO hosting is a bad idea and waste of time because it doesn’t work at all. You can get slap by the Google anytime.
2. The other side says, SEO hosting still work, and they are getting good results from them.

It is a reality that all hosted domain names are mapped to IP addresses, and it is very easy for Google to flag those sites that are linking to each other and hosted on a single IP address. The people who think that use of SEO hosting is dangerous, I think they’re not dangerous if you are hosting just five domains. But your investment could go to waste if you are hosting hundreds of domains. You should keep the following things in mind:

– Google is way smarter than you think. So don’t play with Google.
– Google can check and analyze all the backlinks in a minute to determine whether the same person owns them or not.
