Hello Jose,

the problem explained in 3 steps:

1. domain is delegated to nexusparc.acnet.net:
> clubasur.com.mx.
Server: ns.nic.mx
Address: 200.23.1.1

Non-authoritative answer:
clubasur.com.mx nameserver = nexusparc.acnet.net

2. The domain acnet.net is delegated to:
> acnet.net.
Server: C.ROOT-SERVERS.NET
Address: 192.33.4.12

Non-authoritative answer:
acnet.net nameserver = DNSMTX.acnet.net
acnet.net nameserver = TAG02.acnet.net

Authoritative answers can be found from:
acnet.net nameserver = DNSMTX.acnet.net
acnet.net nameserver = TAG02.acnet.net
DNSMTX.acnet.net internet address = 170.76.16.5
TAG02.acnet.net internet address = 167.114.253.3

3. But these nameservers dont know a host named nexusparc:
> set qt=a
> nexusparc.acnet.net.
Server: DNSMTX.acnet.net
Address: 170.76.16.5

*** DNSMTX.acnet.net can't find nexusparc.acnet.net.: Non-existent
domain

Solution:
Change the delegation at ns.nic.mx to your nameservers or make the
hostmaster
of acnet.net add an A-RR for the host nexusparc.acnet.net.

Hope this helps,
Dirk Pantring.

PS: Some hints:
1.
> -> clubasur.com.mx. in ns 167.114.25.165
make the right side a host name and make sure that there is an A-RR for
that host:
> clubasur.com.mx. in ns nexusparc.acnet.net
(A-RR at acnet.net!)

2.
try not to use serial numbers containing a dot (floats). You need some
workaround compile options to make this work. Better use integers.
I am using format YYYYMMDDnn which works fine.
