#DNSSERV1 – Set DNS Server IP Address

Description: In order to translate the server names from literal format into IP addresses, the TCP/IP stack

software implements the Domain Name System (DNS) protocol. The DNS Server IP address must

be specified for use by the TCP/IP stack software.

Syntax: AT#DNSSERV1="<value>"
