@OmPrasadI think, there is no as such limit defined for length of FQDN to be added as a object. There are only limits on number of objects.

Are you facing any kind of issue for long length FQDN object?




Yes, one of my customer is facing such issue. They have firewall deployed in AWS and they are complaining for length increasing for fqdn.

I know this is an old thread. But so far my analysis show that I am able to resolve upto 63 char FQDN (ver.9.0.6). Recently, received fqdn for rds instance with 68 char and it's just won't resolve.


I believe there is a max as per this old KB but I am not sure what's the max on current ver.
