multiple IPs

How can I get my IPs from this configuration :

me@here:~/nodejs-projects/tim$ ifconfig

enp4s0 Link encap:Ethernet HWaddr 00:04:ac:f3:62:d0

No source file or test is named; start by reviewing node-ip's existing API and the behavior requested for the interfaces shown by ifconfig. Done would require a clearly defined way to retrieve multiple configured IPs, along with documented expected behavior and coverage for this configuration.
