The hint flag is ARES_AI_NUMERICSERV, and it will save a call to getservbyname or getservbyname_r to set it.
This is where the hint flag is used in the C-Ares library -> https://github.com/c-ares/c-ares/blob/main/src/lib/ares_getaddrinfo.c#L645
For context we are trying to make a static binary that can run on any linux box, however that fails as not setting the hint triggers a getservbyname_r calls, which in turn loads the nss libraries which might not be on a different linux box (possible if that box runs alpine).
