Ha, you made me think of casually referring to xkcd's by number just as we did with RFC's back in the day. "I don't know, the socket states seem to follow RFC 793, but remember it's a 1918 address on the southside of the NAT."

I gonna keep a look out for doing this with xkcd's now :)

There are a few that pop out but the one that has managed to stick (aside from 1053 that just came up), is 927 for standards, which you can remember as 3^2 for 9 and 3^3 for 27. Or Yoda's age + the 27 club.
