Resource Records and Zones
To resolve names, servers consult their zones.
The zones contain resource records (RRs) that make up the resource information associated with the DNS domain.
For example, some resource records map friendly names to IP addresses, and others map IP addresses to friendly names.

A record, this is the 32-bit IPv4 address that represents the host defined by the resource record.
- Priority: Specifies the preference given among same type of records.
- TTL: Time to live a 32-bit integer that represents, in seconds, the length of time that a DNS server or resolver should cache this entry before it is discarded. This field is optional, and if it is not specified, BluellaDNS uses the default TTL.

Best Practice to Add Resource Records for a domain :
- Keep blank while adding a resource record to a naked domain.
- Select appropriate record from the drop down list that points to your domain.
- Put appropriate destination value for your domain as per resource record selected.
- Lower priority records are preferred for MX record.
- Always use valid Public IPv4 & IPv6 address for resource record data (RDATA).
- Use "
*" for wildcard entry.
- Never terminate Host names and MNAME with a "
."
- Always click
Commit changes after making any changes in the resource record data.
