After updating the zone file
The default behaviour is to allow zone transfers to any host.While on its face this may seem an excessively friendly default, DNS data is essentially public (that's why its there) and the bad guys can get all of it anyway.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.Understanding DNS and its working is one of the most difficult computer engineering subject and yet most experienced network administrators struggle in this topic when it comes to DNS zone file writing. (see RFC 1912 section 2.3) In the above example we are mapping each NS records to IP address (A record) thus binding nameservers to IP (that is glue them).You can see directly from the domain's control panel whether or not the handle you are logged in under can edit a zone.The solution is to proceed by creating a copy of the zone and then following the instructions here to go through with the normal zonefile edit process.
The simplest way of explaining DNS in one line is to map domain name to IP address. MX records (for mail servers) should contain hostnames NOT IPs.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.The following information is offered in good faith as comprising only safe programming and procedures.However if the thought of anyone being able to transfer your precious zone file is repugnant, or (and this is far more significant) you are concerned about possible Do S attack initiated by XFER requests, then use the following policy.allow-update defines an address_match_list of hosts that are allowed to submit dynamic updates for master zones, and thus this statement enables Dynamic DNS.
