IP Address Resolution

IP Address Resolution

To ensure that users can use the IP address normally, ensure that:

  • An IP address is a network layer address of a host. To transmit data packets to a destination host, the device must obtain the physical address of the host. Therefore, the IP address must be resolved to a physical address.

  • A host name is easier to remember than an IP address. Therefore, the host name needs to be resolved to the IP address.

On Ethernet, the physical address of a host is the MAC address. The DNS server resolves a host name to an IP address. ARP resolves an IP address to a MAC address. For details, see DNS Configuration and ARP Configuration.
