Well Known Services (WKS)
Well Known Service (WKS) record. Describes the well-known TCP/IP services supported by a particular protocol on a particular IP address. WKS records provide TCP and UDP availability information for TCP/IP servers. If a server supports both TCP and UDP for a well-known service or if the server has multiple IP addresses that support a service, multiple WKS records are used. (RFC 1035)
