Public methods
isNumericAddress
public static boolean isNumericAddress (String address)
Checks to see if the address is a numeric address (such as "192.0.2.1" or
"2001:db8::1:2").
A numeric address is either an IPv4 address containing exactly 4 decimal numbers or an
IPv6 numeric address. IPv4 addresses that consist of either hexadecimal or octal digits or
do not have exactly 4 numbers are not treated as numeric.
This method will never do a DNS lookup.
| Parameters |
|---|
address |
String: the address to parse.
This value cannot be null. |
| Returns |
|---|
boolean |
true if the supplied address is numeric, false otherwise. |
parseNumericAddress
public static InetAddress parseNumericAddress (String address)
Returns an InetAddress corresponding to the given numeric address (such
as "192.168.0.1" or "2001:4860:800d::68").
See isNumericAddress(java.lang.String) (String)} for a definition as to what constitutes a
numeric address.
This method will never do a DNS lookup.
| Parameters |
|---|
address |
String: the address to parse, must be numeric.
This value cannot be null. |
