Regular Expression Details

Title Test Find Validate IP port number (1-65535)
Expression
:(6553[0-5]|655[0-2][0-9]\d|65[0-4](\d){2}|6[0-4](\d){3}|[1-5](\d){4}|[1-9](\d){0,3})
Description
This was based on the regex in the source but it was buggy so I fixed it and then optimized it. It matches port numbers in the form of :1 to :65535 This is designed to be plugged onto the end of your favourite url regex because when I was looking for a IPv4 regex I noticed that a lot of them either didn't match the port or matched it badly (allowing the port number to start with a 0 or be higher than 65535) This regex solves those two problems.
Matches
:1 | :65535 | :2546
Non-Matches
:99999 | :0684 | :2ab23

Expression mistyped: second part requests an IP with 6 digits, e.g. 655000 would do. Remove the unnecessary [0-9].
