change ONLY one record in zone
Hello bind gurus! I need to change only one record in zone (not deligated to my server, can't transfer it too) RECORD.DOMAIN.NET IN A 192.168.1.1 to RECORD.DOMAIN.NET IN CNAME RECORD.DOMAIN.ORG Only one record!

search directive in resolv.conf - only 2 domains searched
My resolver only does lookups for the first two domains specified by the search directive in the /etc/resolv.conf file. For example, if I do a lookup of server1.eur.domain2.mil and domain2.mil is the second domain specified by the search directive, the query works. However, if domain2.mil is the third domain specified by the search directive, the query fails. This is behavior that has changed within the last two weeks on our Solaris 9 systems (the Solaris 10 systems still work). The only explanation that I can think of is that the resolver libraries have changed and that the libraries were only compiled to look through the first 2 domains that are specified by the search directive. Is this a possibility? Where are the dns resolver libraries located on a Solaris 9 system?

a question on bind cache
Hello, We have been facing this problem, sometime the original server was down, but Bind didn't know it, and still answered clients with the dead IP. Or sometime an external domain name has two or more IPs, accessing to part of them is fast, but accessing to another part is slow. So, do you think is there a resolving way for Bind which can implement the features: 1. check the popular domains' original IPs (like google's, yahoo's, aol's etc), and exclude the dead IPs from its cache. 2. for the popular domains, testing the access speed to each of their IPs and answers the fast IPs to local clients.

You could monitor your services and then use dynamic DNS to change resource records based on the results, but it's not the best way to go about doing it. To illustrate, you can use a window as a door. It works, but it's not the right thing to do.
