Uses of UnknownHostException in java.net

Methods in java.net that throw UnknownHostException
`static InetAddress[]` | `InetAddress.getAllByName(String host)` Given the name of a host, returns an array of its IP addresses, based on the configured name service on the system.
`static InetAddress` | `InetAddress.getByAddress(byte[] addr)` Returns an `InetAddress` object given the raw IP address .
`static InetAddress` | `InetAddress.getByAddress(String host, byte[] addr)` Create an InetAddress based on the provided host name and IP address No name service is checked for the validity of the address.
`static Inet6Address` | `Inet6Address.getByAddress(String host, byte[] addr, int scope_id)` Create an Inet6Address in the exact manner of `InetAddress.getByAddress(String,byte[])` except that the IPv6 scope_id is set to the given numeric value.
`static Inet6Address` | `Inet6Address.getByAddress(String host, byte[] addr, NetworkInterface nif)` Create an Inet6Address in the exact manner of `InetAddress.getByAddress(String,byte[])` except that the IPv6 scope_id is set to the value corresponding to the given interface for the address type specified in `addr`.
`static InetAddress` | `InetAddress.getByName(String host)` Determines the IP address of a host, given the host's name.
`static InetAddress` | `InetAddress.getLocalHost()` Returns the local host.

Constructors in java.net that throw UnknownHostException
`Socket(String host, int port)` Creates a stream socket and connects it to the specified port number on the named host.

Uses of UnknownHostException in javax.net

Methods in javax.net that throw UnknownHostException
`abstract Socket` | `SocketFactory.createSocket(String host, int port)` Creates a socket and connects it to the specified remote host at the specified remote port.
`abstract Socket` | `SocketFactory.createSocket(String host, int port, InetAddress localHost, int localPort)` Creates a socket and connects it to the specified remote host on the specified remote port.

Uses of UnknownHostException in javax.net.ssl

Constructors in javax.net.ssl that throw UnknownHostException
`SSLSocket(String host, int port)` Used only by subclasses.
`SSLSocket(String host, int port, InetAddress clientAddress, int clientPort)` Used only by subclasses.
