Question

I have a variable packet of type DatagramPacket. While packet.getAddress().toString() results in a String representing an the IP address, it has an extra / appended to the beginning of the String:

/127.0.0.1

I can easily remove the leading '/', but is there a better way to just obtain a string representation of the IP? I am worried because what if there are more '/' in other situations.

Thanks!

Answer 1

Use the following:

packet.getAddress().getHostAddress()

From the documentation:

Returns the IP address string in textual presentation.

Contrast that with InetAddress.toString():

Converts this IP address to a String. The string returned is of the form: hostname / literal IP address. If the host name is unresolved, no reverse name service lookup is performed. The hostname part will be represented by an empty string.
