Introduction [RFC4791] defines the CalDAV calendar access protocol, based on HTTP [RFC2616], for accessing calendar data stored on a server. CalDAV clients need to be able to discover appropriate CalDAV servers within their local area network and at other domains, e.g., to minimize the need for end users to know specific details such as the fully qualified domain name (FQDN) and port number for their servers. [RFC6352] defines the CardDAV address book access protocol based on HTTP [RFC2616], for accessing contact data stored on a server. As with CalDAV, clients also need to be able to discover CardDAV servers. [RFC2782] defines a DNS-based service discovery protocol that has been widely adopted as a means of locating particular services within a local area network and beyond, using DNS SRV Resource Records (RRs). This has been enhanced to provide additional service meta- data by use of DNS TXT RRs as per [RFC6763].
