How long after making a modification to a DNS zone does it take for the changes to take place.
I added the www and ip to a zone because the website was not resolving when using the "www." prefix only when leaving it out. Im not exactly sure why this wasnt automatically added, but i added it manually and you can still only access the domain without using the prefix.
Depends on what changes you make. First time to resolve a new domain name can take 1-5 days. SOA record changes a matter of hours. One of the best sources to see changes is dnsreport.com
Makes it easy to tune dns settings.
