Then, the command ipconfig /renew is executed to request a new IP address. [3] [4] Where a computer is connected to a cable or DSL modem, it may have to be plugged directly into the modem network port to bypass the router, before using ipconfig /release and turning off the power for a period of time, to ensure that the old IP address is taken ...
PC/TCP Packet Driver is a networking API for MS-DOS, PC DOS, and later x86 DOS implementations such as DR-DOS, FreeDOS, etc.It implements the lowest levels of a TCP/IP stack, where the remainder is typically implemented either by terminate-and-stay-resident drivers or as a library linked into an application program.
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.
IP address management (IPAM) is a methodology implemented in computer software for planning and managing the assignment and use of IP addresses and closely related resources of a computer network. It does not typically provide Domain Name System (DNS) and Dynamic Host Configuration Protocol (DHCP) services, but manages information for these ...
In order to connect to a computer running TCP/IP via its NetBIOS name, the name must be resolved to a network address. Today this is usually an IP address (the NetBIOS name to IP address resolution is often done by either broadcasts or a WINS Server – NetBIOS Name Server). A computer's NetBIOS name is often the same as that computer's host ...
Users type in domain names, such as example.org, which the computer's DNS software looks up in the DNS databases to retrieve an IP address, and then hands off that address to the protocol stack for further communications. [5] Looking up an address using DNS requires the IP address of the DNS server to be known.
The network controller implements the electronic circuitry required to communicate using a specific physical layer and data link layer standard such as Ethernet or Wi-Fi. [a] This provides a base for a full network protocol stack, allowing communication among computers on the same local area network (LAN) and large-scale network communications through routable protocols, such as Internet ...
PCP allows equipment and applications to create explicit mappings between an external IP address, protocol and port, and an internal IP address, protocol and port. With such explicit mappings in place, inbound communication can reach the hosts behind a NAT or firewall, which either expands their server roles beyond boundaries of local networks ...
