They're standard notation for CIDR address prefixes. 192.168.0.0/22 means
that that it should match the high-order 22 bits of an address against
192.168.0.0. 192.168.0/22 is equivalent -- trailing 0's are implied. /24
is a class C, /16 is a class B, and other numbers are subnets, supernets,
etc.

Don't forget that caching servers will do their own round-robin, they don't
preserve the order that the originating server gave out. Also, you need
the same sorting in slave servers -- it's not transmitted in zone
transfers.
