AltostratusBIg-IP DNS Listener question
Hello Folks, I'm having hard time understanding how a listener and wide IP works in the Big-IP DNS realm. Hoping to get an answer here. I understand that Listener on Big-IP DNS listens and...
You need to delegate the zone for production.company.com from company.com
So the zone file for company.com contains the following records:
production.company.com NS ns1.production.company.com production.company.com NS ns2.production.company.com ns1.production.company.com A 1.1.1.1 ns2.production.company.com A 2.1.1.1So when someone queries www.production.company.com, they will send a NS query to a .com nameserver for company.com, and get a reply.
They then send a NS query to the company.com nameserver asking for a production.company.com nameserver.
The company.com nameserver replies that an NS record for production.company.com is at ns1.production.company.com, and to help you out, the A record for ns1.production.company.com is 1.1.1.1.
The client then sends a www.production.company.com A record request to 1.1.1.1 which resolves the WideIP for 1.1.1.1.
This is a standard DNS zone delegation, and your DNS provider or manager should be able to set this up without any difficulty at all.

EmployeeYou need to specify the IP of the listeners as the NS records for the domain that you want to return WideIPs for.

AltostratusThe domain i want to use is owned by our public DNS provider and as per registrar i can only use the name server from the provider.
For example, I want to use production.company.com and company.com is owned by a public DNS provider say ATT and so do the name servers.
