We have a *.mydomain.com setup in godaddy A-type record pointing to same IP address. The problem occurring that occasional some domains are resolving to correct IP address and one subdomain does not. after some random time, it also works perfect. and this also happens differently to machines within the same network.
machineA can't resolve a.mydoamin.com, machineB can. machineA and machineB both can resolve b.mydoamin.com
We have dns expiry/TTL set to 24 hours. Please suggest.
Im also thinking to try to resolve wildcard with a CNAME of mydomain.com. could it work?
