The document discusses several Internet protocols: - IP prepares packets for transmission across the Internet and provides unreliable packet delivery. IPv6 was created to address issues with IPv4 like exhaustion of addresses. - ARP resolves IP addresses to hardware addresses on local networks and maintains address mappings in caches. - ICMP provides error reporting and network monitoring functions to support IP. - TCP provides reliable data transmission and UDP provides simple transmission of datagrams.
