What is the correct behaviour when Nameservers Change
I registered a domain at GoDaddy and changed the nameservers to my server's. (GoDaddy sets up the domain using their own nameservers initially.) Now, almost 24 hours later, how come when using some ISPs you get forwarded to my nameservers, whereis for some it still is the old entry? I guess there is some form of caching involved.
Is there some way to know when all users will be routed to my nameservers? And more generally, how can I learn more about the underlying principles?
