Match IP and Port number withing parantheses

Question

I am trying to fetch the IP addr and Port no separately from a given string.

STRING: 
(10.10.2.5:1567)

I need the O/P as

10.10.2.5
1567

I am new to RegEx and the pattern I am using is

\(([\d.]+):\d+\).*

This one seems to pick 10.10.2.5 but fails to pick the 1567

Answer 1

Use this regular expression:

\(([\d.]+):(\d+)\).*

Its is essentially the same regex as yours with the following 2 changes:

1. Escape the parenthesis "(" and ").
2. Add second capture group to get the port number.

So $1 will have the IP address and $2 will have the port number.

Answer 2

You can use this pattern

\d+[.]\d+[.]\d+[.]\d+(:\d+)?

Answer 3

You are capturing IP address with the first group

([\d.]+)

but not the port. You need another pair of parenthesis to define the second group

\(([\d.]+):([\d]+)\).*

Notice that the first group is also too generic: it will accept any mix of digits and dots:

23424....2342423
