How to Locate IP, Gateway, Subnet and DNS Information

An Internet Protocol (IP) address is a unique number that can identify each host (computers, routers, switches, etc.) on a network. When a host sends information to the IP address of a second receiving host it includes IP of origination, IP of destination and other information. Knowing the IP address of key network components such as routers, firewalls and servers, can be useful when troubleshooting network problems. Use of utilities like Ping or Trace Route can help isolate problem areas.

A knowledge of relevant network topology and settings including DNS, gateway and subnet mask can also be useful when exploring network issues.

Domain Name Service (DNS) numbers are IP addresses that a workstation or server uses to refer to specific servers that resolve domain names to IP addresses.

A gateway IP refers to a device on a network which sends local network traffic to other networks.

The subnet mask number helps to define the relationship between the host (computers, routers, switches, etc.) and the rest of the network. How to Locate IP, Gateway, Subnet and DNS Information | Technical Support | MOREnet
