That "2(5".. part is strange and wrong. What you are trying to do with it? According to Wikipedia [1], the range is 172.16.0.0 - 172.31.255.255 So maybe 172\.(1[6-9])|(2\d)|(3[01])\.\d\d?\d?\.\d\d?\d? That will be 16-19, 20-29, 30-31 for the second byte. (I'd be better to have some unit tests, to be sure).
