Today I noticed I'm getting a bunch of icmp echoes from 69.12.21.169, which PTRs to a.icmp-monitor.noc.sonic.net. Since I spotted elsewhere on the forum that active icmp monitoring is something to expect more of in the future, I thought I'd be a better citizen on the sonic network and whitelist it.
It doesn't look like there's more than one of these in my logs yet, and {b,c}.icmp-monitor.noc.sonic.net NXDOMAINs. Does anybody know if there's an address range listed for these anywhere?
