How come when setting name server records, so you can work out what IP address a domain belongs to, you always use domains?
How come they can work out what IP address the name servers refer to?
Why aren't IP addresses used? Surely that would be more efficient? For a domain name lookup, it has to go:
- find out name server address
- resolve name server address to IP address (eg, ns1.hostingcompany.com to xxx.xxx.xxx.xxx)
But if IP addresses were used rather than host names, it could skip the second step?
