first there is the arguments about whether reverse zones are useful and
should be populated. i happen to use reverse lookup daily, so i try to
maintain them well for all the address space for which i am responsible.
so, given that i am gonna maintain the zone, why would i not want to
also sign the data? the amount of work is trivial, and it's just one
more step in trying to paint security on the horribly insecure internet.
otoh, some ipv6 providers (ahem!) do not seem to sign reverse parents in
ip6.arpa, so it can be hard to get one's delegated /56-48 properly DSed.
