hi those domain are public available and we have a internal dns which is
domainA and contain all the record from internal and also external.DomainA is
also public available and we have bought an hardware balancer which contain 2
public ip address and we like the hardware to do the load balance instead of
using the window round robin.Let said when i ping mail.domainA.com it will
reply with mail.balancer.domainA.com.And when you do an nslookup to these
external dns which run on redhat it will show as below
main.domainA.comServer: servername.balancer.domainA.com
Address: public ip
Aliases: servername.domainA.com
Name: main.domainA.co,
Served by:
- ns1.balancer.domainA.com
public ip A
balancer.domainA.com
- ns2.balancer.domainA.com
public ip b
balancer.domainA.com
And as said these load balance is done on the hardware level and it is not
on the dns, if i add two record on the dns it is already run on dns
level.Kindly advise how should i approach

hi,
I have a question on the dns, if i have a domain A and B when I ping
domain A it will go to domain B, these can be done by using forwader
on the dns, but now my question is, if we dont use any forwarder can
we complete these task?will like to output the result when we do
nslookup on domain A, it will said these record is servered by ns1 or
ns2.kindly advise on the steps
No, not a forwarder, but a CNAME will do that, such as when you ping FQDN A,
but B's IP replies.
If I misunderstood, can you provide an example of exactly what you are
pinging and the results please? Are these public domains, such as are you
pinging 'example-A.com' and the IP from 'example-B.com' replies?
As for nslookup, there are a number of features and commands that can be
used to do various things. If you type in:
nslookup
set q=SOA
domain.com
it will tell you who domain.com's nameservers are. Is that what you are
looking for?
