I setup up a HTTP server in home that is connected to the internet. I registered .COM a domain. Now I want to use this domain to connect to my server. but when i try to set my IP address as DNS I see this error :
Unable to update nameservers: Nameserver [MYIPADDRESS] doesn't exist at the registry
Nameservers indicates what server owns the DNS records for the zone, you need to create A records, not update the Nameserver. If you are on GoDaddy, switch to the "DNS Zone File" tab and then create an A record instead of trying to change the nameserver records.
