CNAMEs and ip-addr.arp

[tnaves at linkwest.net]

I have a host with an A record:

host IN A 192.168.1.50

I have two others which are aliases of host:

hostess	IN CNAME host
mostess	IN CNAME host

in db.1.168.192.in-addr.arpa I have a PTR reord for host:

50.1.168.192 IN PTR host

My question is:

Is there a way to have reverse lookup records for hostess and mostess,
which are aliases of host?

Thanks,

Tom Naves
