Like this (for IPV4):

... | rex max_match=0 "Client\s+IP:[\r\n\s\d\.\,]*(?<!\d)(?<Client_IP>\d+\.\d+\.\d+\.\d+)"

I do note that you have an IPV5 IP in your example???

[DalJeanis]

If IPV5 is in play, then you probably want

 ... | rex max_match=0 "Client\s+IP:[\r\n\s\d\.\,]*(?<!\d)(?<Client_IP>\d+\.\d+\.\d+\.\d+(\.\d+)?)"

or

 ... | rex max_match=0 "Client\s+IP:[\r\n\s\d\.\,]*(?<!\d)(?<Client_IP>\d+(\.\d+){3,4})"

[woodcock]

Yes, I could have accommodated it but I figured it was a mistake/typo.

Is this what you're looking for?

| rex field=_raw "(IP\:\s+|\d+\,)(?P<ClientIP>.*)."
| makemv delim="," ClientIP 

This should extract the IPs and separate them into their own values.
