Nothing needs to be setup in Win95 to allow reverse DNS; this has to be
configured at your DNS server. A "forward" lookup is "find me the
address for this name", an "reverse" lookup is "find me the name for
this address."

The ISP would have to have setup their DNS server to support both types
of lookups. If you're experiencing problems, they probably haven't.
Try this: dial in and check your IP address. We'll assume you were
given the address 204.203.202.201, because it's fun to type. Login to
a good UNIX system somewhere and type 'nslookup -type=ptr
204.203.202.201'. If you get an name back quickly, and can 'nslookup
name' and get 204.203.202.201 as the IP address, you're correctly
configured. If not, your ISP is at fault and needs to fix their DNS
server.
As several others have pointed out, the reason ping and http work
quickly is because they are not doing reverse DNS lookups. If you want
to really test your ability to do reverse DNS, try logging into
ftp.uu.net as user 'anonymous'. If they let you login, you're probably
doing just fine. ;^)
