How to extract values with regex

[Chethan GR]

I want to extract the data from ticket description and store it in a text field using automation for Jira in cloud. Let's say my ticket description (Created via email) has Server IP and client name in the following format,

Server: 11.22.33.44

Client: ABC

For IP address Regex code :- 

"(?:(?:25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)\\.){3}(?:25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)"
