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. |
