Monday marks a quarter century of classless routing, or CIDR.

25 years since Class A, B, and C addresses were the standard.

On #CIDRDay, saying "class C address" outside a historic/ironic context is a request for enthusiastic wedgies.

Otherwise: cider!

How will you celebrate? #sysadmin #netadmin

Seriously: if you can't handle enough binary math to do CIDR, or you can't use a cheat sheet and remember a few basic netmasks, you shouldn't be a #netadmin.
@mwlucas well, thank glob i picked up Javascript b/c i know i cant do that.

@somarasu I appreciate a person what knows his limits.

And I'm confident you could learn. I mean, if Mr English Degree here can do it, anyone can.
