Final answer:
RFC 349 and RFC 1700 both relate to Internet protocols, with RFC 349 discussing multicast transport and RFC 1700 assigning numbers for Internet protocols and other purposes.
Step-by-step explanation:
RFC 349 and RFC 1700 are both related to Internet protocols. These documents are part of a series of technical and organizational notes about the Internet, known as Request for Comments (RFCs). RFC 349 is titled "Multiple Sequence Numbers in Reliable Multicast Transport Protocol (RMTP)", while RFC 1700 assigned numbers, which was later obsoleted by RFC 3232 and further replaced by an online database maintained by IANA, the Internet Assigned Numbers Authority.
