This is a list of the IP protocol numbers found in the field Protocol of the IPv4 header and the Next Header field of the IPv6 header. It is an identifier for the encapsulated protocol and determines the layout of the data that immediately follows the header. Both fields are eight bits wide.
By setting the forwarding agent (FA) to one of the routers that the packet must visit, LSR is equivalent to tunneling. If the corresponding node stores the LSR options and reverses it, it is equivalent to the functionality in mobile IPv6. The name loose source routing comes from the fact that only part of the path is set in advance. [4]
NAT Port Mapping Protocol (NAT-PMP) is a network protocol for establishing network address translation (NAT) settings and port forwarding configurations automatically without user effort. [1] The protocol automatically determines the external IPv4 address of a NAT gateway, and provides means for an application to communicate the parameters for ...
For link-local addressing, IPv4 uses the special block 169.254.0.0 / 16, [1] while IPv6 hosts use the prefix fe80:: / 10. More commonly addresses are assigned by a DHCP server, often built into common networking hardware like computer hosts or routers. Most IPv4 hosts use link-local addressing only as a last resort when a DHCP server is ...
Mobile IP (or MIP) is an Internet Engineering Task Force (IETF) standard communications protocol that is designed to allow mobile device users to move from one network to another while maintaining a permanent IP address.
Packet Forwarding Control Protocol (PFCP) is a 3GPP protocol used on the Sx/N4 interface between the control plane and the user plane function, specified in TS 29.244. [1] It is one of the main protocols introduced in the 5G Next Generation Mobile Core Network (aka 5GC [ 2 ] ), but also used in the 4G/LTE EPC to implement the Control and User ...
Polipo, a discontinued forwarding and caching HTTP/1.1 proxy server with IPv4 support. Open Source running on Linux, OpenWrt, Windows, Mac OS X, and FreeBSD. Almost any Web browser can use it. Privoxy, a non-caching SOCKS-to-HTTP proxy. Tinyproxy, a light-weight HTTP/HTTPS proxy daemon for POSIX operating systems. Designed from the ground up to ...
Port Control Protocol (PCP) is a computer networking protocol that allows hosts on IPv4 or IPv6 networks to control how the incoming IPv4 or IPv6 packets are translated and forwarded by an upstream router that performs network address translation (NAT) or packet filtering.
