Evening all
I am looking to implement an internal DNS system that will respond with
a record that is specific to the users network. Let me explain. I am
looking to implement a number of caching engines out to over 300 remote
sites that are part of a large private (network 10) WAN. Presently all
hosts on the network are configured to look to a specific caching engine
cluster using RR -DNS with the host address, lets say, host.domain.com
(in laymen's terms all Internet browsers on the network are configured
to use host.domain.com as there proxy). To avoid having the burden of
having to change all remote clients browsers to accommodate the roll out
of caching engines to the remote sites, I wish to implement a DNS
resolution system that will therefore give a response to a request for
host.domain.com as the local caching engine on site rather than the
caching engines on the core of out network. Make sense?
To provide an example, if I was on the network 10.1.1.1/255.255.255.0
and my new caching engine had the address 10.1.1.30, then my DNS (on the
core of the network serving all sites) would intelligently respond to
all clients on the network 10.1.1.1/255.255.255.0 who requested
host.domain.com with the address 10.1.1.30. Likewise, if I was on the
network 10.1.2.0/255.255.255.0 and my new caching engine was 10.1.2.30
then the DNS would respond for me with that address.
I've briefly looked at the functionality that Bind9 provides with regard
to split DNS and views (External and Internal responses) but the
documentation is not clear that this can achieve what I want so does
anyone have any experience in getting this working to the sort of
solution I am looking for?
I am currently running Bind 8.2.2 on RH7.0 as an internal DNS system but
would be *very keen* to upgrade to 9 should it provide me with this
functionality.
TIA
