nslookup shall prefer one address

Peter Klausner_1 — Fri, 27 Sep 2002 10:06:01 GMT

Hi,

is there a possibilty to determine the order of Ip-Addresse when making an nslookup

example:
root @ ovhost-prod> nslookup ovhost

Trying DNS
Name: ovhost.systor.com
Addresses: 10.122.13.66, 10.122.28.66, 10.122.13.65

The list of IP-Addresses shall start with 10.122.13.65

Thanks ind advance

Peter

Hi,
yes , it depends on the order of your A records
placed in your zone data file.
for example
If the order is like this

ovhost IN A 10.122.13.65
ovhost IN A 10.122.28.66
ovhost IN A 10.122.13.66

Then nslookup will present like this
(dont forget to restart named after this change)

Name: ovhost.systor.com
Addresses: 10.122.13.65, 10.122.28.66, 10.122.13.66

dont forget to restart named after this change

Hi,

the order plays no role. The whole process seems to be random.

Hi,
sorry , misunderstood your question

IF you are using BIND 9 , there is no way to stop this randomness.

But in BIND 8 it is possible ,

put the A records as i told you in my previous
post.

Edit /etc/named.conf and put this rrset-order option

options {
directory "/var/named/";

rrset-order { order fixed; };

};

restart named.

that's it.

Hi,

thank you for the hint.
I put the following line in the /etc/named.boot

options no-round-robin

Now it works
