Field Details

SUPPORTS_V6

@Deprecated
public static final boolean SUPPORTS_V6

Deprecated.

transition mechanism only, do not use

True if we can bind to a v6 address. Its silly, but for *binding* we have a need to know if the stack works. this can prevent scary noise on IPv4-only hosts.

Method Details

sortAddresses

@Deprecated
public static void sortAddresses(List<InetAddress> list)

Deprecated.

remove this when multihoming is really correct

Sorts addresses by order of preference. This is used to pick the first one for publishing

defaultReuseAddress

public static boolean defaultReuseAddress()

Returns system default for SO_REUSEADDR

getAllAddresses

public static InetAddress[] getAllAddresses()
                                     throws IOException

Returns all addresses (any scope) for interfaces that are up. This is only used to pick a publish address, when the user set network.host to a wildcard

Throws:

IOException

getAllIPV4Addresses

public static InetAddress[] getAllIPV4Addresses()
                                         throws IOException

Returns:

all IPv4 addresses for interfaces that are up.

Throws:

IOException

getAllIPV6Addresses

public static InetAddress[] getAllIPV6Addresses()
                                         throws IOException

Returns:

all IPv6 addresses for interfaces that are up.
