  2. List of TCP and UDP port numbers - Wikipedia

    en.wikipedia.org/wiki/List_of_TCP_and_UDP_port...

    This is a list of TCP and UDP port numbers used by protocols for operation of network applications. The Transmission Control Protocol (TCP) and the User Datagram Protocol (UDP) only need one port for duplex, bidirectional traffic. They usually use port numbers that match the services of the corresponding TCP or UDP implementation, if they exist.

    The oldest anarchy server in Minecraft; there is no officially set list of rules, allowing the use of cheats and obscene language ingame. Its map is one of the longest-running server maps in the game. It has since updated to Minecraft version 1.20 after previously running on Minecraft version 1.12 for many years.

    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.

  5. Port (computer networking) - Wikipedia

    en.wikipedia.org/wiki/Port_(computer_networking)

    The operating system's networking software has the task of transmitting outgoing data from all application ports onto the network, and forwarding arriving network packets to processes by matching the packet's IP address and port number to a socket. For TCP, only one process may bind to a specific IP address and port combination.

  6. Port forwarding - Wikipedia

    en.wikipedia.org/wiki/Port_forwarding

    Port forwarding via NAT router. In computer networking, port forwarding or port mapping is an application of network address translation (NAT) that redirects a communication request from one address and port number combination to another while the packets are traversing a network gateway, such as a router or firewall.

  7. Zero-configuration networking - Wikipedia

    en.wikipedia.org/wiki/Zero-configuration_networking

    Each host listens on the mDNS port, 5353, transmitted to a well-known multicast address and resolves requests for the DNS record of its .local hostname (e.g. the A, AAAA, CNAME) to its IP address. When an mDNS client needs to resolve a local hostname to an IP address, it sends a DNS request for that name to the well-known multicast address; the ...

  8. STUN - Wikipedia

    en.wikipedia.org/wiki/STUN

    The STUN server responds with a success response that contains the IP address and port number of the client, as observed from the server's perspective. The result is obfuscated through exclusive or (XOR) mapping to avoid translation of the packet content by application layer gateways (ALGs) that perform deep packet inspection in an attempt to ...

  9. IP address - Wikipedia

    en.wikipedia.org/wiki/IP_address

    IP addresses are assigned to a host either dynamically as they join the network, or persistently by configuration of the host hardware or software. Persistent configuration is also known as using a static IP address. In contrast, when a computer's IP address is assigned each time it restarts, this is known as using a dynamic IP address.
