Well, it actually depends on what your packages does. If its goal
involves examining the IP addresses active on the system's interfaces,
then you should bear in mind that addresses added by "ip addr add"
will not be shown in ifconfig's output.
[roam@debian ~]$ sudo ip addr add 127.10.0.5/16 dev lo
[roam@debian ~]$ sudo ip addr list | fgrep inet
inet 127.0.0.1/8 scope host lo
inet 127.10.0.5/16 scope host lo
inet6 ::1/128 scope host
inet 10.100.0.85/24 brd 10.100.0.255 scope global eth0
inet6 fe80::21a:4bff:feb1:824c/64 scope link
[roam@debian ~]$ sudo ifconfig | fgrep inet
inet addr:10.100.0.85 Bcast:10.100.0.255 Mask:255.255.255.0
inet6 addr: fe80::21a:4bff:feb1:824c/64 Scope:Link
inet addr:127.0.0.1 Mask:255.0.0.0
inet6 addr: ::1/128 Scope:Host
[roam@debian ~]$
Just something to bear in mind - whether it actually affects your
package depends on exactly what your package does with ifconfig :)
G'luck,
Peter

If there were no counterfactuals, this sentence would not have been paradoxical.
