- *
- * IP-address/hostname to country converter.
- *
- * Problem; you want to know where IP a.b.c.d is located.
- *
- * Use ares_gethostbyname ("d.c.b.a.zz.countries.nerd.dk")
- * and get the CNAME (host->h_name). Result will be:
- * CNAME = zz<CC>.countries.nerd.dk with address 127.0.x.y (ver 1) or
- * CNAME = <a.b.c.d>.zz.countries.nerd.dk with address 127.0.x.y (ver 2)
- *
- * The 2 letter country code is in <CC> and the ISO-3166 country
- * number is in x.y (number = x*256 + y). Version 2 of the protocol is missing
- * the <CC> number.
- *
