I'm not sure what type of filtering you're trying to do, but one possible regular expression which will capture the IPs you referred to is this:
192<.>168<.>.*<.>8 172<.>18<.>.*<.>.*
The brackets around the literal dots are optional and included for clarity. And if you're only matching IP addresses, then everything after the first .* in the 172 expression is also optional.
