Records and answers

A DNS record is a data entry within a DNS zone containing certain information (answers) about a domain or subdomain. The context of the record data depends on the record type. One of the most common record types are "address" (A or AAAA) records which specify the IPv4 or IPv6 address(es) of the application host. Whereas, traditionally, each record contains one answer, an NS1 Connect record may contain multiple answers. This enables you to define record-level traffic steering policies using the Filter Chain.

A DNS answer is a unit of information within a DNS record containing specific details about the domain, such as the IP address for an application endpoint or service. The nature and format of each answer depend on the record type. When the record is queried, the answer(s) specified in the record configuration are returned in the DNS response. Unlike traditional DNS providers, the NS1 Connect platform supports multiple answers per record, eliminating the need to duplicate records for each answer and enabling advanced traffic steering functionality using the Filter Chain.
