FM station transmitting numbers

I'm in the US and a station near me, 91.9 has been transmitting numbers for the past few days, 168 dot 192 dot 0 dot 164 dot, for example. It then waits about two minutes and transmits another string of numbers. I know numbers stations transmit AM so is it some sort of error code?

It's either an IP address, or a one time pad, one way transmission . As an IP address, what you've listed goes nowhere because it's incomplete. It's probably a one time pad transmission. Where are you at?
