Network Name Resolution

Addressing remote nodes using a raw IP address is not always practical because:

• IP addresses can change.
• The IP address of a remote computer might not be known.
• IP addresses are not very memorable.

It is more convenient to address a remote node using a human readable name. The process of converting a human readable name into an IP address is called Name Resolution. FreeRTOS+TCP includes DNS, LLMNR and NBNS implementations for this purpose.
