Any device connected to the IP network must have a unique IP address within the network The previous regex does not actually limit email addresses to 254 characters. If each part is at its maximum length, the regex can match strings up to 8129 characters in length. You can reduce that by lowering the number of allowed sub-domains from 125 to something more realistic like 8 In ip address the maximum number in our range is 255 which is three characters long. Minimum number is 0 which is one character long. To write a regex for matching this range 0-255 we will breakdown this range into smaller ranges which can be easily managed for writing regex. So the breakdown i

Regex flavors: .NET, Java, JavaScript, PCRE, Perl, Python, Ruby. Simple regex to extract IP addresses from longer text: \b (?: [0-9] {1,3}\.) {3} [0-9] {1,3}\b. Regex options: None. Regex flavors: .NET, Java, JavaScript, PCRE, Perl, Python, Ruby To restrict all 4 numbers in the IP address to 0..255, you can use the following regex. It stores each of the 4 numbers of the IP address into a capturing group. You can use these groups to further process the IP number. Free-spacing mode allows this to fit the width of the page This regular expression is too simple - if you want to it to be accurate, you need to check that the numbers are between 0 and 255, with the regex above accepting 444 in any position. You want to check for 250-255 with 25 [0-5], or any other 200 value 2 [0-4] [0-9], or any 100 value or less with ? [0-9] [0-9] Create a regular expression to check valid MAC address as mentioned below: regex = ^ ( [0-9A-Fa-f] {2} [:-]) {5} ( [0-9A-Fa-f] {2})| ( [0-9a-fA-F] {4}\\. [0-9a-fA-F] {4}\\.

For geographical or language reasons, the format of an address varies all over the world. Here's a long list describing these formats per country. Since address format is too varied, it's impossible for a regex to cover all these patterns.
