I have domain in one company, with an specific NS entries, but I don't want changes the NS entries.
The server is in another company with public IP.
If I want to point from my domain to the server, is enough with adding an A record into the domain company, that A entry would point to my public IP.
Is that OK?
How long it takes the changes?
How can I trace the A record propagation?
A
records is the "OK" thing to do in the first place and have just leapt in with the assumption that it is.
