DNS trouble

Allan Spagnol Comar
Hi All, I am having a little problem with my DNS server; I using a DNS
server at 210.200.1.230;
when I do nslookup dnsserver.com.br it returns 210.200.1.230
when I try nslookup 192.168.0.2 it return ** server can't find
230.1.200.210.in-addr.arpa: NXDOMAIN

does someone have a clue about what is going on ?

Yes, `nslookup' is fundamentally broken. Try `host' or `dig' (with its
`-x' option) instead.

And don't expect RFC 1918 address space to be resolvable via a public
name server...

still the problem

allan@thewho ~ $ host 210.200.1.230
Host 230.1.200.210.in-addr.arpa not found: 3(NXDOMAIN)
allan@thewho ~ $ host 210.200.1.232
232.1.200.210.in-addr.arpa domain name pointer shakan.commodity.com.br.

and seems to me that both shakan.eng.com.br and thewho.eng.com.br is
configured equal at the zones; the diference is the thewho (
210.200.1.230 ) is my DNS server.

You have to give more information here. 192.168.0.2 is a private IP address.
So a NATting firewall has to be involved. Would you give an overview over
your network? You probably need to set up DNS with an outside and an inside
view.

On thing sis clear: The reverse lookup table for 192.168.0 isn't there.

[driver@beavis ~]$ dig -x 210.200.1.1 | grep AUTHORITY\ SEC -A 1
;; AUTHORITY SECTION:
1.200.210.in-addr.arpa. 10733   IN      SOA     dns.ht.net.tw.
root.dns.ht.net.tw. 1999090230 10800 3600 3600000 86400

Are you dns.ht.net.tw. ??? If not, then you need to contact them to get
the reverse fixed. You can either allow them to give you authority over
your address space, or they can add the names to their
1.200.210.in-addr.arpa file on the DNS.

for your internal DNS, you setup your own .in-addr.arpa files for the
192.169.0.0/16 subnets that you use.
