The
A Record is made up by the association between a host name and the relevant IPv4 address.
With the DNS management service it is possible to enter multiple A Records. These records can be changed or deleted at any time. If you wish you can associate the A Record to an IP address connected to a Cloud Server: to do this simply select the data center on the right, the Cloud Server and an associated IP address. This IP address will be automatically displayed in the IPv4 address field.
For the configuration of the A Record you will need:
Host,
IPv4 Address,
TTL.
The Host represents the third level of the domain to which the DNS is associated and will therefore look like this:
nomehost.domainname.ext
This parameter is optional.
The IPv4 address has a series of four blocks of numbers (from "0" to "255") separated by a "dot" ( . ) and looks like the following:
192.128.35.124
This parameter is mandatory.
The TTL (Time-To-Live) represents the time, calculated in seconds, that is given to the cache DNS to store information of a host before interrogating the authoritative DNS again; or rather it’s the time required to spread on the web a change made to the DNS. Therefore a whole number must be indicated, for example:
86400
So you will have: 60 for 1 minute, 3600 for 1 hour, 86400 for 1 day, 604800 for 1 week, etc ...
This parameter is optional.
