Bulk Class C IP Address Checker

Test Duplicate IP Address :: Help - Class C IP Address Checker

Additional Notes On How To Use This Site

Formats

When entering your list, either manually or using a text file, the tool will except the following domain address formats:

Note: these should all be in lower case

ip-report.com

www.ip-report.com

http://www.ip-report.com

http://ip-report.com

So there is no need to spend time making the list uniform if you have copied and pasted it from a variety of places.

The tool will also accept page and directory domain names, e.g.

http://www.ip-report.com/site-map.htm

http://www.ip-report.com/sample

Duplicate Definitions

A Y in the Class C Duplicate column means that there is at least one other domain in the list with the same class c block address, e.g.

66.225.255.xyz and 66.225.255.xyz where xyz can be any number

A Y in the Subnet Duplicate column means that there is at least one other domain in the list with the same class c block subnet address, e.g.

66.225.255.131 and 66.225.255.131

Sort Functions

If you click on the report column headers (Domain URL, IP Address, Class C Duplicate or Subnet Duplicate) the report will sort for that column, click again and it will sort in the opposite order.

This is useful when you have a very long list of domains and you want to bring the duplicate to the top of the list.

Test File

If you want to do a quick test of the tool before building your own domain list copy and paste the sample list below:

Clear All

Always use the Clear All button between loading different domain lists to ensure results integrity.

Performance

There is no specific limit to the number of domains that can be tested.

During testing of the tool a list of 220 domains was checked in 5-10 seconds on an ordinary residential broadband internet connection. Obviously if a dialup connection is used the processing time could be longer.
