I don't know if you WANT to have 2x, or just 2., it would of been better
if you provided what you tried. Nonetheless, I've done both for you

This would include 60.40.any.any:
(eg: 60.40.171.199)

grep "60.40.[0-9]\{1,\}.[0-9]\{1,\}"

This would include 60.40.2.any (but not 60.40.2x):
(eg: 60.40.2.199, not 60.40.20.199)

grep "60.40.2.[0-9]\{1,\}"

This would include 60.40.2any.any:
(eg: 60.40.219.199 or 60.40.21.199)

grep "60.40.2[0-9]\{1,\}.[0-9]\{1,\}"

...and this would include 60.40.2x.any
(eg: 60.40.22.199, but not 60.40.212.199)

grep "60.40.2[0-9]\{1\}."

HTH,

Steve
