Subnet sensitve DNS??

[geoff_durham at hotmail.com]

I am after a solution that allows a DNS server to resolve the same
hostname to different IP addresses based on the requesting client's
subnet/location.

i.e.

Client A (subnet 157.128.81.0) resolves server1.orgname.com to
157.128.81.2
Client B (subnet 157.128.89.0) resolves server1.orgname.com to
157.128.89.2

Both clients are resolving the hostnames from the same DNS server

Is this possible???

Regards,
Geoff
