Additional Information: IP addresses, IP range, and domain name formats

Here is a list of all of the correct formats you could use with IP Blocker:

Single IP Address – If you want to block one IP address, use the standard IP format of four sets of numbers, each separated by a dot. For example, 193.166.0.2

Range – If you want to block a range of IP addresses, list the first and last of the range you wish to block and separate them with a hyphen/dash. For example, 193.166.0.2-193.166.0.50

Implied Range – This is a shorthand way to input a range. For example: 193.166.0.2-50

Implied IP address – This uses a truncated version of an IP address to bulk block all IP addresses that follow the last used dot. For example, input 193. would block all IP addresses which start with 193. Similarly, inputting 193.166. would block all IP addresses beginning with 193.166.

Domain name – It uses the domain name. For example, website.com. The full URL is not required to be filled in. Once this is put in, IP Blocker will try to find the domain’s IP address for you.
