CirrusF5 DNS for External websites
Greetings everyone,
I require assistance with F5 DNS resolution for external websites. I have a website hosted on GoDaddy, for example, mapmap.org. Currently, it points to a single A record, and I aim to implement load balancing between the IPs. To achieve this, I configured a wideip named mapmap.xxx.org and created aliases for mapmap.org and www.mapmap.org. also, pointed Godaddy DNS to my F5 DNS listener IP /NS by removing A record in Godaddy dns.
Subsequently, Zonerunner was set up with SOA and NS, using the F5 Listener IP. Upon performing an nslookup, I successfully obtained the answers. However, I noticed a .org. zone created as self, with these alias records falling under that zone.
Is it acceptable to have a zone with .org and include these alias records, or is there an alternative approach for this configuration? I appreciate any assistance provided.

it's better if you share the dns records in godady and f5 config.
usually, f5 dns implementaiton using dns record is like this:
Origin:: a. In godaddy: host1.mycompany.com IN A 1.2.3.4 host2.mycompany.com IN A 11.12.13.14 host3.mycompany.com IN A 21.22.23.24 New using F5 DNS:: a. In godaddy: declare new subdomain to be NS-ed by F5 DNS and create alias record for previous A records f5dc1.mycompany.com IN A 5.6.7.8 /// Datacenter1 F5 DNS listener address f5dc2.mycompany.com IN A 15.16.17.18 /// Datacenter2 F5 DNS address f5dns.mycompany.com IN NS f5dc1.mycompany.com f5dns.mycompany.com IN NS f5dc2.mycompany.com host1.mycompany.com IN CNAME host1.f5dns.mycompany.com host2.mycompany.com IN CNAME host2.f5dns.mycompany.com host3.mycompany.com IN CNAME host3.f5dns.mycompany.com b. In F5 DNS: create wideip configs for host1.f5dns.mycompany.com, host2.f5dns.mycompany.com, host3.f5dns.mycompany.com which basically serves: host1.f5dns.mycompany.com IN A .... //IP address is decided dynamically by F5 DNS host2.f5dns.mycompany.com IN A .... //IP address is decided dynamically by F5 DNS host3.f5dns.mycompany.com IN A .... //IP address is decided dynamically by F5 DNS
ashkI agree with the config you said, but it is good for *.mycompany.com. its a subdomain and TLD. I have only top level domain .org like example www.mapmap.org where there is no company name or subdomain. Wanted to see how to achive in this scenario.

so basically originaly you have these records in godaddy:
mapmap.org IN NS ...godady name servers...
mapmap.org IN A ....you webserver public ip adress...So in godaddy, you still need to delete "mapmap.org IN A ..." and create subdomain and alias such as:
f5dns.mapmap.org IN NS ... f5dc1 and f5dc2...
mapmap.org IN CNAME host1.f5dns.mapmap.org

Today, I tried this and getting empty response for mapmap.org and its working for anything.mapmap.org.
Toplevel domain is not working. :( returning and empty response.
