Help: setting a CNAME record for the domain

[Tal Dayan]

Hi Erik,

Thanks for the info. It is strange that we need to go through this just to
have such a simple thing (is there a deep issue here that I miss, can
anybody comment on this ?)

Your #2 suggestion is interesting but I need more help since I am a newbie
to
DNS. We don't have a .com zone file on our server. If we will add it, do we
need to remove the teiko.com zone file or is BIND smart enough to combine
the entries related to teiko.com from the two zone files ?

Also, if we go with the patch approach, what about our outsourced secondary
DNS servers, will they know how to handle this ?

And if this patch does not create a problem with the rest of the DNS world,
how about submitting your patch to the Bind maintainers, asking to include
this great feature with a runtime switch that enable / disabled it.

Thanks,

Tal
