I am not an expert in regex, but it looks to me like you could do this
with two expressions.  One would be to match 111.222.333.11 followed by a
3 through 9, such as '111.222.333.11[3-9]' and one for a .12 followed by a
0 through 6 like '111.222.333.12[0-6]'.  You could also combine this into
an or statement, such as '(111.222.333.1)(1[3-9])|(2[0-6])'
