This is the new IPv6. It is a valid IP address so the code works. It is just a new version of IP as the old version wasn't able to generate enough different IP addresses for all devices connected to the internet. More information can be found on Wikipedia.

The method Formatter.formatIpAddress is deprectaed. It will work for ipV4 addresses but when you’ll have to get the ipV6 address it may fail.

Hey man, the IP address is 32 bits, same as a java integer so IT IS an integer. Thanks for the first snippet, that is all I need, as Im only interested in my wifi IP address. The other snippet is good if you need the IP address of your cellular data connection.

Hi, the best way to get the IP out of wifiInfo.getIpAddress() return integer is:

String ipString = String.format(
“%d.%d.%d.%d”,
(ip & 0xff),
(ip >> 8 & 0xff),
(ip >> 16 & 0xff),
(ip >> 24 & 0xff));

There are a lot of possible problems: Mainly the port is not free. Check your router if he supports the used port. Another possibility is that your service provider blocks the port. Try a default port like 80 and check if the router forward this port to the correct IP address. Another possibility: Is the IP address the correct one? You need to check the IP from the internet of your laptop.
