Increase in query time after upgrading F5 DNS from version 12 to 13

Hi Experts,

 

We are encountering this behavior in DNS version 13, wherein there are multiple timeouts in DNS query but still able to get the IP. Having multiple timeouts made the query time longer.

 

application delivery
BIG-IP DNS
devops
dns timeout
dns_query
f5_dns
LTM

    Check the wideip configuration, if you have enabled IPV6 option? Make sure you unckeck it. It will solve issue. Still same, paste screen?

      Hi I just remember that we are not using WIP. On our testing we are querying on the A record of DNS resource.
