Also, "host" in 3.2 can find CNAMEs, so it does not follow the CNAME. I think it does an ANY search. > ========================================================= > From FreeBSD-2.2.8 (this is the right ansver) > ========================================================= > bash-2.02$ host 212.109.34.132 > Name: extra.gc.lviv.ua > Address: 212.109.34.132 > Aliases: In this case, the "CNAME" has been followed. Probably because "host" did a PTR search instead of any ANY search. Whether "host" follows the CNAME or not is irrelevant. gethostbyname() should still do the right thing.
