The Internet Protocol and other network addressing systems recognize three main addressing methodologies;
- Unicast addressing uses a one-to-one association between destination address and network endpoint: each destination address uniquely identifies a single receiver endpoint.
- Broadcast or multicast addressing uses a one-to-many association, datagrams are routed from a single sender to multiple endpoints simultaneously in a single transmission. The network automatically replicates datagrams as needed for all network segments (links) that contain an eligible receiver.
- Anycast addressing routes datagrams to a single member of a group of potential receivers that are all identified by the same destination address. This is a one-to-one-of-many association.

Famous quotes containing the word addressing:
“He took up his pen, which seemed to parch like a martyr in his hand. He began to write, nevertheless, addressing the nine-and-ninety lies of the moment he hoped with for a night of saloperie at the side of the twisted strumpet, Fiction, who lasciviously rolled her eyes at him, hiked up her skirt, and beckoned him on.”
—Alexander Theroux (b. 1940)
