Par défaut Re: dns query

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.com

Server: 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
