DNS Global Names

Earlier DNS technology does not provide unique name resolution globally. i.e there exists multiple domains across many zones with same name. DNS Global Names provides unique name resolution globally.

The following shows the working of the DNS Global Names for single global name resolution.

1. DNS Client sends DNS query for a NETBIOS Name by appending the Domain Suffix to the DNS Server.
2. If DNS Server hosts the Global Name Zone, then the DNS Server first look in
to the Global Name Zone for the name and if foound sends response to dns
client.
3. If name is not found in the Global Name Zone and WINS server exists, then
queries wins server for name resolution
4. if the above fails, dns looks for authoritative dns zone for the name is
checked.
