|
static Cidr
|
cidr(java.lang.String cidr)
returns a CIDR object for the given string, e.g. "10.0.0.0/8" |
static java.lang.String
|
getAddressOfUnresolvableHostname()
|
static java.net.InetAddress
|
getInetAddressWithFixedName(byte[] ip)
Gets an InetAddress using the given IP, and using that IP as the hostname (i.e. avoids any hostname resolution). |
static java.net.InetAddress
|
getInetAddressWithFixedName(int ip1, int ip2, int ip3, int ip4)
|
static java.net.InetAddress
|
getInetAddressWithFixedName(int ip1, int ip2, int ip3, int ip4, int ip5, int ip6)
creates a byte array given a var-arg number of (or bytes or longs); checks that all values are valid as _unsigned_ bytes (i.e. in [0,255] ) |
static java.net.InetAddress
|
getInetAddressWithFixedName(java.lang.String hostnameOrIp)
|
static java.util.Map
|
getLocalAddresses()
returns all local addresses |
static java.net.InetAddress
|
getLocalHost()
returns local IP address, or 127.0.0.1 if it cannot be parsed |
static Cidr
|
getPrivateNetwork(java.lang.String ip)
|
static Cidr
|
getPrivateNetwork(java.net.InetAddress address)
returns whether the IP is _not_ in any private subnet |
static boolean
|
isLocalOnly(java.net.InetAddress address)
|
static boolean
|
isLocalOnly(java.lang.String hostnameOrIp)
|
static boolean
|
isPortAvailable(int port)
|
static boolean
|
isPortAvailable(java.net.InetAddress localAddress, int port)
|
static boolean
|
isPortValid(java.lang.Integer port)
|
static boolean
|
isPrivateSubnet(java.net.InetAddress address)
Check if this is a private address, not exposed on the public Internet. |
static boolean
|
isPrivateSubnet(java.lang.String hostnameOrIp)
As isPrivateSubnet(InetAddress) but taking a string; sepcifically local-only address ARE treated as private. |
static boolean
|
isPublicIp(java.lang.String ipAddress)
|
static boolean
|
isValidIp4(java.lang.String input)
checks whether given string matches a valid numeric IP (v4) address, e.g. 127.0.0.1, but not localhost or 1.2.3.256 |
static int
|
nextAvailablePort(int port)
returns the first port available on the local machine >= the port supplied |
static java.net.InetAddress
|
resolve(java.lang.String hostname)
resolves the given hostname to an IP address, returning null if unresolvable or if the resolution is bogus (eg 169.* subnet or a "catch-all" IP resolution supplied by some miscreant DNS services) |

public static java.net.InetAddress getInetAddressWithFixedName(byte[] ip)
This is very useful if using the InetAddress for updating config files on remote machines, because then it will not be pickup a hostname from the local /etc/hosts file, which might not be known on the remote machine.
