Search Again: Re: PTR records and reverse zone authority From: Erich Kaminsky Date: Tuesday, August 10, 1999 Time: 9:37:00 pm Actually I seem to have worked this all out by simply removing resolution to any of the secondary ip numbers. I am using a Netopia Router and OT's Secondary IP Address File to assign multiple IP's to the same machine. Until I got your most recent post I was not aware that Quick DNS Pro could not recognize anything but the primary IP number. I am using QDNS v 2.1 As soon as I made 206.117.128.36 my primary IP and resolved DNS, Web, and Mail to that same number everything began to hum like a sewing machine. Thanks for all of your help. >>I wouldn't be surprised at all if I've configured something incorrectly. >> >>The names and adresses are as follows: >> >>mail.usconnect.com ............. 206.117.128.35 >>ns1.usconnect.com .............. 206.117.128.36 >>ns2.usconnect.com .............. 206.117.128.46 >>virtual web resolves to ....... 206.117.128.34 >> >>Everything except ns2.usconnect.com .... 206.117.128.46 is on the same >>machine. > >So you're using multiple IP addresses on your main server?
