Your problem is greatly simplified by the fact that you don't want to
*validate* IP-adresses, but just find valid ones in a logfile:
/10\.3\.\d{1,3}\.\d{1,3}/

Again, just finding, not validating:
/\d{1,3}\.\d{1,3}\.\d{1,3}\.\d{1,3}/
Depending on the format of your logfile, you may want to further
anchor the pattern by whitespace or an other separator.
