Regular Expression for URL / IP with Port Number

Hi,

I need to validate (URL or IP) with port number, please give me a good regular expression for this

Examples:

http://10.25.144.25:1020

http://10.25.15.254

https://www.domain.suffix:1250

http://www.domain.suffix

https://www.domain.suffix

https://domain.suffix

Thanks in advance,

Praneeth Avula.

A regex to validate all of that can become pretty involved if you require validation of TLD's, IP addresses, of RFC standards and such. The following will only really attempt to prevent invalid characters in the domain/ip and ensure a valid port if provided:

boolfoundMatch=Regex.IsMatch(SubjectString,@"(?:https?|ftp)://[-a-zA-Z0-9.]+(:(6553[0-5]|655[0-2][0-9]|65[0-4][0-9][0-9]|6[0-4][0-9][0-9][0-9]|\d{2,4}|[1-9]))?");
