Validates IPv4 IP Address

POSIX ERE compatible, suitable for usage in Bash [ testing Attributions Derived from [regex101: RFC1918 - Private IPv4 addresses by 0100101101001.

Finds the protocol, subdomain, ((domain, extension)/ipaddress), port, filepath (split in path and filename), the route and the query string.

(!-\~][aeiou)

Handle all condition for ipv6 example: 1) FE80::8329 2) FE80::FFFF:8329 3) FE80::B3FF:FFFF:8329 4) FE80::0202:B3FF:FFFF:8329 5) FE80::0000:0202:B3FF:FFFF:8329 6) FE80::0000:0000:0202:B3FF:FFFF:8329 7) FE80:0000:0000:0000:0202:B3FF:FFFF:8329

Match an ipv6 address

Validate IPv4 addresses using PCRE's recursion patterns. A shorter but less efficient alternative to https://regex101.com/r/wZ6oY5/1

This regular expression will match an IPv4 address as well as both compressed or uncompressed IPv6 address.

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

It's too large to match with all which seems like an IPv6. It's not perfect, but it's detects more valid IPv6 than some others regex.

Get ip address (only ipv4) Validator

A good enough approximation to IPv6 based on the examples at https://www.ibm.com/docs/en/ts3500-tape-library?topic=functionality-ipv4-ipv6-address-formats

Validate a given IP v4 address against all three defined Private IPv4 Subnets as statet in RFC1918 10.0.0.0/8 172.16.0.0/20 192.168.0.0/16 Wikipedia Link RFC Link

This regex matches every IPv4 address with or without 0s before every number. For example: 192.168.1.1 00000000000192.168.00000000000001.01

Parse "ipconfig /all" output and grab all MAc Adresses.

Ensure the ip address format is correct

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

Valid: 000.01.249.255 1.199.200.0 0.0.0.0 Invalid: 1000..256.300

Blocks IPs that are sent in discord. Will block any IP, even if the numbers aren't in valid ranges (like 327.19.8.79) Has basic protections against whitespace

Validate an IPv4 address. The addresses are four numbered separated by three dots, and can only have a maximum value of 255 in either octet. Start by trying to validate 172.16.254.1.

Intentionally leaves out weird stuff such as IPV4 or IPV6 for the domain part and quoted usernames with invalid chars in the addressee part. Handles internationalized domains with soft validation (only structural matching) and blocks domain parts starting or ending with dashes or containing double dashes (except in xn-- internationalization prefix).

IPv4 Address Input

Regex to match an IPv4 address at beginning

Searches for dotted decimal IPv4 Adresses and saves the numbers in match groups.

Capture 0.0.0.0-255.255.255.255 IP address octets. Capture private ranges, such as '169.254.' and '10.'

Simple Regex to *validate * (no extraction!) an IPv4 Range which can be a comma separated mixture of IPv4 addresses IPv4 CIDRs IPv4 Ranges like 1.1.1.1-1.1.1.10 Examples : 192.168.1.1,255.255.255.255/32,10.10.10.10/24,0.0.0.0/24 192.168.1.1/32 192.168.1.1 192.168.1.1/32 192.168.1.1/12 192.168.1.1/24 192.168.1.1/24 192.168.1.1/0,192.168.1.1/0 10.0.0.0/24 172.16.0.1-172.16.0.255 192.168.1.1,10.0.0.1/24,172.16.0.1-172.16.0.10 64.33.232.212 64.33.232.210/24

Match only Private IPv4 Does not match Public IPv4 and test Nets

Match only Public IPv4 Does not match Private IPv4 and test Nets

Match only Public IPv4 Does not match Private IPv4 However does match test Nets

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

IPv4 matching pattern. Excludes values over 255 or numbers with zero-prefix (e.g. 08)

This regular expression strictly matches an IPv4 address. Leading 0 are not matched , take a look at test strings and try your own ones.

(?(?:(?: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)

Parse stdout from ipmitool sensor

Regex pattern detection for IPv4 addresses and IPv6 addresses in zero compression format.

Strict validator for IPv4 with optional CIDR Disallows 00 in any octet

Match and validate both ipv4, ipv6 and CIDR notation mask!

Helps to find IPv4 or IPv6 CIDR entry in any text.

IPv6 前缀格式

Converts in-addr.arpa hostnames to IPv4 e.g. 1.0.0.127.in-addr.arpa to 127.0.0.1
