Thanks, based on the comments of the readershp I was able to solve several issues like the subdomains within the dynamic zone. I was also concerned that slave-updates within a fully dynamic zone might eat LOTS of traffic, many of my users are using ISDN-dialup to 50 times a day making lots of changes to my dynamic zone. With a big zone this easily adds up to 10GB/month. So I have vital interest in running the dynamic zone on one nameserver, not two. This might be of interest for you: At a "smart"-TLD like .de or .at you can't give twice the same nameserver, DENIC puts quite some effort into detecting such rubish - you can't enter twice the same IP or Names which resolve to the same IP. You need two fully independend Nameservers running in different /24-nets. A "dump"-TLD like .cx just tries to catch the really obivous stupid. If I enter IPs, they must differ. But if I only enter fully qualified domain names I can use the same name twice. My first tries based around ns.dyn.cx, thats why I needed to apply IP-addresses and failed. When I changed my mind to work with ns.psi5.com I was able to supply exaktly one nameserver to NICCX, which looks like Domain Name: dyn.cx Creation Date: 2002-04-05 02:25:07 Expiration Date: 2003-04-05 02:25:07 Last Modified: 2002-05-31 09:45:50 Nameservers: NS.PSI5.COM And thats exactly what I need and how it works now. I guess you could fool DENIC or other "smart" NICs into similar behaviour by supplying two FQDN pointing to different nameservers (eg ns1.example.net 1.2.3.4 and ns2.example.net 2.3.4.5) but changing them to one IP after first initialisation (ns1.example.net and ns2.example.net 3.4.5.6). -- Christian Brandt life is short and in most cases it ends with death but my tombstone will carry the hiscore _______________________________________________________________ Don't miss the 2002 Sprint PCS Application Developer's Conference August 25-28 in Las Vegas -- http://devcon.sprintpcs.com/adp/index.cfm -- GnuDIP Mailing List http://gnudip2.sourceforge.net/gnudip-www/#mailinglist
