Domain name to ip address

DNS 서버로 IP address 를 조회해서 출력하는 듯.

InetAddress inetAddress = InetAddress.getByName("www.google.co.kr");

System.out.println(inetAddress);

System.out.println(inetAddress.getCanonicalHostName());

System.out.println(inetAddress.getHostName());

System.out.println(inetAddress.getHostAddress());

결과

www.google.co.kr/74.125.71.94
