Why is ifconfig with 4 values?

  • 772

I have output like this

ifconfig | grep "inet addr"
          inet addr:*.18.0.1  Bcast:0.0.0.0  Mask:255.255.0.0
          inet addr:*.17.0.1  Bcast:0.0.0.0  Mask:255.255.0.0
          inet addr:*.168.0.12  Bcast:192.168.0.255  Mask:255.255.255.0
          inet addr:127.0.0.1  Mask:255.0.0.0

This is what I got 

ifconfig | awk '/Link encap:/ {print $1}'
br-498e85899682
docker0
enp3s0

Why do I have four IP addresses?
