GTM DNS Questions

1. the client request goes to their LDNS, the LDNS then uses recursive queries to find the IP address, once it has an IP then it provides it to the initiating client who then makes a separate connection to the IP address.

 

 

2. You generally define 2+ name servers and the only thing we cant control is which NS is given out, if we take an example of 2 NS then each NS will be used about 50/50 although there are different methods used to dish these out depending on the DNS server (MS, UNIX etc) although generally each one will be used roughly 50% of the time. This means that both the GTM's will receive queries although we adjust the GTM load balancing method to decide which site we want clients to be load balanced to.
