Validates IPv4 IP Address

(!-\~][aeiou)

validate an IP v4

This is a regex to validate the format of an IPv6-based CIDR range, where the IPv6 portion can be standard, mixed, and/or compressed notation. Supported by: .NET, Java, JavaScript, PCRE, Perl, Python, Ruby Adapted from IPv6 regex published in Regular Expressions Cookbook

This regexp was written for Regex Tuesday Challenge - Week Six.

An IPv4 expression that doesn't allow leading zeros in octets. 10.0.0.1 will pass 10.0.0.01 shouldn't pass

(?(?:(?:250-5]|(?:2[0-4]|1\d|[1-9]|)\d)\.?\b){4}) Originating from ^((25[0-5]|(2[0-4]|1\d|[1-9]|)\d)\.?\b){4}$ at only 43 chars Source: [Danail Gabenski

This regex can be used to validate IPv4 and IPv6 addresses as well as CIDR ranges

Matches any valid IPv4 address with, optionally, a CIDR suffix. 0.0.0.0 to 255.255.255.255 and 1.1.1.1/0 to 1.1.1.1/32. Use the following regex if you don't want to allow the CIDR suffix. /^(?:(?:1-9]?[0-9]|1[0-9|2(?:0-4|50-5]))\.){3}(?:[1-9]?[0-9]|1[0-9|2(?:0-4|5[0-5]))$/ (removed (?:\/(?:[12]?[0-9]|3[0-2]))? from the end)

Matches IPv4 address list separated by comma (,). Does not match an incomplete list (e.g. 192.168.1.0,)

This performs a non-rigorous validation of IPv6 addresses. Should be used before handing off the value to a better parser/validator.

This will match valid IP addresses which are listed in RFC1918. 127.0.0.0 - 127.255.255.255 10.0.0.0 - 10.255.255.255 192.168.0.0 - 192.168.255.255 172.16.0.0 - 172.31.255.255
