Please note: The incorrect editing of your zone file can take your site offline.
All editing must be done on the authoritative nameservers for the given domain.
For example, if your website is hosted on Host Gator then the name server used to manage your DNS records will be Host Gator’s generic name servers, like this: NS1.NS2.NS3.Each domain name must have at least two name servers. NET Domain registrars usually provide domain owners easy tools to manage their name servers.
The first name server is the primary server, however if the primary server is not responding then the secondary name server is used to resolve the domain name. Ideally it would be best if you register domain with hosting provider, this way you will not have to deal with transferring domain name or changing name servers.
The purpose of DNS is to use easy to remember domain names for websites instead of their numeric IP addresses.
It also enables website owners to change their web hosts without changing domain names.

A guide to lowering the TTL values can be found here.
