I will reference in the future. Good point. Sometimes too much information just muddies the water and I try to ask clear questions as much as possible. If I throw too much at someone they may run and hide.
As for the code eth0 has no IPv4 information in it, but does have IPv6, so that is why the data returns empty. Here is the output of ifconfig

I need this thing to not care about who has what. Not be dependant on IPv4 being satisifed. If IPv4 info is there print it. if IPv6 info is there print that too. Frustrated trying to figure that out.
yesterday I mistakenly said What is garanteed is v4 data. What is not garanteed is which NIC the v4 data will be on and if there will be any v6 data and now I am realizing some nic devices could have IPv4 only, IPv6 only, or both. Can you or someone help me get that piece fixed? |
