Best way to add/set an ipv4 LAN address in java

Question

I'm interested in adding an additional ipv4 local network ip address from a java application (actually Scala). So far, the only solution I've found is runtime exec of netsh , but I'd prefer not to have a dependency on netsh and use core java libraries if possible. What's the best solution for this? Moreover, it looks like even netsh won't work for me since I'm on linux.

Answer 1

You could make a call to ifconfig (or ipconfig / netsh for windows).

Using the following command:

ifconfig eth0 <NEW-IP> netmask 255.255.255.0 up

In Java:

Process p = Runtime.getRuntime().exec(new String[]{"bash","-c","ifconfig eth0 <NEW-IP> netmask 255.255.255.0 up"});
