true if there is no domain name in the hostname (no dots).

dnsDomainIs

public static boolean dnsDomainIs(String host,
                                  String domain)

Returns true if the domain of hostname matches.

Parameters:

host - the hostname from the URL

domain - the domain name to test the hostname against

Returns:

true if the domain of hostname matches.

localHostOrDomainIs

public static boolean localHostOrDomainIs(String host,
                                          String hostdom)

Returns true if the hostname matches exactly the specified hostname, or if there is no domain name part in the hostname, but the unqualified hostname matches.

Parameters:

host - the hostname from the URL

hostdom - fully qualified hostname to match against

Returns:

true if the hostname matches exactly the specified hostname, or if there is no domain name part in the hostname, but the unqualified hostname matches.

isResolvable

public static boolean isResolvable(String host)

Tries to resolve the hostname. Returns true if succeeds.

Parameters:

host - the hostname from the URL.

Returns:

true if the specific hostname is resolvable.

isInNet
