Synopsis

Description

CTL_IP_CONFIG_t contains the values needed to configure the IPv4 layer of the network library. If DHCP is not used, the application code must supply one of these structures to ctl_net_init during startup.

ip_addr

Our IP address in network byte order.

subnet_mask

Our subnet mask in network byte order.

gateway

Local router (gateway) address in network byte order. This can be zero if packets never leave the LAN.

dns_primary_server

Primary DNS server IP address in network byte order. This can be zero if DNS is not used.

dns_secondary_server

Secondary DNS server IP address in network byte order. This can be zero if DNS is not used or there is no secondary DNS server.

ttl

Time to live for outgoing IP packets. Generally a ‘don't care’ for use on a LAN.
