`docker ps` sorts IPs lexicographically instead of numerically

[hirehamir]

Description

When a container publishes ports on multiple IPs, docker ps orders them by the string form of the IP, so 10.0.0.2 sorts before 9.0.0.1.

Current behavior:

127.0.0.10:8080->80/tcp, 127.0.0.9:8081->80/tcp

Reproduce

docker run -d --name porttest -p 127.0.0.9:8081:80 -p 127.0.0.10:8080:80 nginx:alpine

docker ps

Expected behavior

127.0.0.9:8081->80/tcp, 127.0.0.10:8080->80/tcp
