Reverse DNS on non-network .0 addresses

[Chris Tata]

I am able to do reverse on every other IP on the /24 block, just not .0

When we acquired our /22 from our current provider I was having some issues
with reverse DNS on the first half of the network.  When I noticed ARIN's
whois information didn't show my company as providing reverse authority for
the IP block, I put in a trouble ticket.  My current uplink assured me that
they had delegated me authority for each of the zones.  Sure enough, I
was/am able to do reverse on our delegated IP's.  The only IP's I am having
problems reversing are the non-network .0 addresses (66.153.41.0 and
66.153.42.0).

I noticed that with our old provider, who also provided us a /22, when I did
a whois query on ARIN's whois servers it showed my uplink as the primary
owners of the IP's and it had a section below it to denote that my company
provided reverse authority for that block.  I guess I don't know enough
about IP authority delegation yet to call and yell at my provider (maybe I
dont need to).

Thanks guys,

Chris
