AI analysis

null.cz is the parent of dev.null.cz.

null.cz is delegated to two name servers: dev.null.cz and puck.nether.net.

Host names with two IP numbers:

dev.null.cz points to 2a01:430:34:0:2:0:dead:babe and 80.79.26.115

puck.nether.net points to 2602:fe55:5::5 and 204.42.254.5

null.cz is handled by a single mail server, dev.null.cz.
