Or you could directly map the addresses into their name space: 1 CNAME 1.addr.example.com. 2 CNAME 2.addr.example.com. where example.com is your client's domain. On the client side they have to maintain only one zone file for example.com: www.example.com A 10.1.1.1 1.addr.example.com PTR www.example.com. etc. --Renaud > -----Original Message----- > From: dan@nfol.com [SMTP:dan@nfol.com] > Sent: Monday, May 24, 1999 6:22 AM > To: mark@intrepid.net > Cc: freebsd-isp@freebsd.org > Subject: Re: BIND and subnetted in-addr.arpa domains > > > > We have a dedicated access customer who wants to run reverse > > DNS on the subnet that we're routing to him.
