I am not sure how many would know that when somebody types a domain name in IE/firefox, the browser forwards the DNS request asking for ip address from the resolver of ISP (ISP Provider) and the resolver contacts the root servers and then systematically retrieves the IP address within a matter of few milliseconds. Glue records are A records that are associated with NS records to provide "bootstrapping" information to the NS records nameserver.

To assign a different IPv4 address to the mail server, perform the following steps: The system cannot perform automatic detection for this setting if the MX entry does not resolve (for example, if you mistype a domain name or enter one that does not exist).
allow-notify applies to slave zones only and defines a match list, for example, IP address(es) that are allowed to NOTIFY this server and implicitly update the zone in addition to those hosts defined in the masters option for the zone.
If it's authoritative 'aa' flag in the header will be set in the answer received ('aa' is authoritative answer). flags: qr aa rd Since 'aa' is set in the answer, then both the nameservers of provide authoritative answer.
This means that if you have just added an entry in your zone file, you will then have between 0 and 20 minutes to wait before your addition is reflected in the zone. This time is necessary because we regenerate the entire zone each time, and it takes a while to replicate it on all the servers.
The default behaviour is to allow zone updates only from the masters IP(s).
This statement may be used in a zone, view or global options clause. IP address(es) that are allowed to transfer (copy) the zone information from the server (master or slave for the zone).
The example shows DDNS for three zones: the first disables DDNS explicitly, the second uses an IP-based list, and the third references a key clause.
