Do hosts list support "a.b.example.com"?

[ivynetworks]

Firewall/Aliases/ IP Hosts do not support "a.b.example.com"?

it will never be matched if I add an entry "a.b.example.com", only "a.example.com" is fine.

Please verify.

Thanks

When you put FQDNs in an alias like that they are resolved by filterdns when the ruleset is built.
Anything that the firewall can resolve should work correctly there.
