DNS Zones and Resource Records

DNS zone resource records are a complex type that contains the resource records for the current resource record set. Using the editor, provide an Array of JSON objects, each containing one ‘Value’ attribute. You can provide as many value’s as you like in the Array.

[
  ...
  {
    "Value": "some.record.value"
  },
  {
    "Value": "\"a text record needs to be in quotes!\""
  }
  ...
]

NOTE: a TXT records requires double quotes, so be sure to escape them!

TTL

Time to live is what dictates how long it will be until your computer refreshes its DNS related information. For example, the IP address your domain name points to or where your MX records are directing email.

This time is defined in seconds and the default setting can be found in the zone file. The reason this is useful is that if you will be moving hosts, or if you have any sort of DNS information that you need to change, it will take affect in a shorter time interval.

Generally, DNS propagation takes 24 to 48 hours to complete whenever any changes are made to the Zone File. Lowering the TTL prior to making the change will reduce the time for propagation.

Let’s say you want to change your email from your (mt) Media Temple account to Google Apps. If you make this change now, with the default TTL of 43,200 seconds (12 hours), it will be up to 12 hours until all the email is directed at Google.
