DNS server IP address 1. The address can be either IPv4 or IPv6 address. An optional port number can be given. Following syntax is supported: 192.0.2.1 192.0.2.1:5353 2001:db8::1 [2001:db8::1]:5353 It is not mandatory to use this Kconfig option at all. The one calling dns_resolve_init() can use this option or not to populate the server list. If the DNS server addresses are set here, then we automatically create default DNS context for the user.

Direct dependencies¶

DNS_SERVER_IP_ADDRESSES && DNS_RESOLVER && NETWORKING

(Includes any dependencies from ifs and menus.)
