A Record is short for Address Record. It maps a domain name to an
IP address. Below is an example of an A Record in the LoadDNS admin.
Host Name: Your domain name www.loaddns.com is the Host Name
TTL (Time to Live): The TTL number 1200 is in seconds and corresponds to how long the record stays cached in other systems. The lower the TTL number is, the higher the query count will be. This is because, if the A record isn't cached in other systems they have to query our DNS servers thus increasing the query count.
Weight: While editing A records weight informs LoadDNS how to weight the order and at what frequency to rotate round robin records as they are returned from our servers.
IP Address: 209.58.232.100 is the IP address that your Host Name (domain name) maps to
