DNS is an internet service that maps domain names, like rosettacode.org, to IP addresses, like 66.220.0.231.

Use DNS to resolve www.kame.net to both IPv4 and IPv6 addresses. Print these addresses.




- Option.map (NetHostDB.toString o NetHostDB.addr) (NetHostDB.getByName "www.kame.net");
val it = SOME "203.178.141.194": string option
