Method Detail

resolve

java.util.Collection<java.net.InetAddress> resolve(java.lang.String host)

Resolves a hostname to one or more IP addresses. The iterator over the returned Collection is recommended to reflect the ordering returned by the underlying name lookup service. For example, if a DNS server returns three IP addresses, 1.1.1.1, 2.2.2.2, and 3.3.3.3, corresponding to www.somehost.com, the returned Collection iterator is recommended to iterate in the order [1.1.1.1, 2.2.2.2, 3.3.3.3].

Parameters:

host - host to resolve

Returns:

resolved InetAddresses, or an empty collection if no addresses were found
