Primary DNS servers are sometimes called preferred DNS servers and secondary DNS servers are sometimes called alternate DNS servers. Primary and secondary DNS servers can be "mixed and matched" to provide another layer of redundancy.

In general, DNS servers are referred to as all sorts of names, like DNS server addresses, internet DNS servers, internet servers, DNS IP addresses, etc.
