Follow-up Comment #2, bug #60569 (project lwip):

ip_addr_t is sized to fit any IP address supported in the build - so there
should not be any out of bounds writes at least. Did you see memory corruption

Switching from ipaddr_ntoa to ip4addr_ntoa seems like a step away from v4/v6
compatibility as the former handles both.
