Here's how you would match 172.16. through 172.32.
/^172\.(1[6-9]|2[0-9]|3[0-2])\./

Note that periods mean "any single character".  So to refer to a literal period, you need to escape it with a backslash first.  However, since every combination you're looking for ends with a period, you could just specify it once at the end.

/^(0|10|44|127|169\.254|172\.(1[6-9]|2[0-9]|3[0-2])|192\.168|224)\./

Isn't it 169.254. ?

Maybe it is worth to put 172.16.|172.17.|...|172.31. into the list (if
it will not "break" the line :D)
