## ◆ IP6_ADDR_ANY

#define IP6_ADDR_ANY (&ip6_addr_any)

IP6_ADDR_ANY can be used as a fixed ip_addr_t for the IPv6 wildcard address

## ◆ IP6_ADDR_ANY6

#define IP6_ADDR_ANY6 (ip_2_ip6(&ip6_addr_any))

IP6_ADDR_ANY6 can be used as a fixed ip6_addr_t for the IPv6 wildcard address

## ◆ ip_2_ip6

#define ip_2_ip6 | ( |  | ipaddr | ) | (&((ipaddr)->u_addr.ip6))
