So I'm building a trusted FQDN list (including 3rd party for sites to load fine) for HTTPS mostly it works fine but have found a problem that ZLD is doing correctly but not uOS.

So if I have FQDN
*.grc.com

Go to www.grc.com it loads fine but if I try grc.com it does not and I think the problem has to do with the IP lookup for each so if I go www.grc.com the IP is 4.79.142.202 then if I go to grc.com the IP is 4.79.142.200 but I never see IP 4.79.142.200 for *.grc.com in IPv4 Cache List but in ZLD it Caches both IP's correctly.

Could this be fixed please

Edit more info

On old ZLD you can do

*grc.com

or

*.grc.com

but with the new uOS you can only do

*.grc.com

with ZLD and *grc.com it Caches both grc.com and www.grc.com
