In the JSON output you'll see something similar to this: "Subnet": "172.18.0.0/24", You can determine which networks are claiming which subnets by using docker network inspect 28881c0a72ad. Those "bridge" entries map to the "br-" prefixed entries seen in the ip addr listing.

To determine what IP addresses docker itself is using, we can use the ip addr command to see what addresses the networking bridges claim. Looking at this above data, we can derive that the IP address between the ranges of 172.16. Connect to your VPN first then run this command. You can easily find which IP addresses are being used by your local network or VPN by using route -n. These are usually in the local networking space, which include the following:
When you start up Docker, it appropriates some IP addresses for it's own usage. It turns out a frequent culprit of this problem is Docker and it's networking mechanisms. Occasionally when accessing a client network, I encounter a situation where certain servers are not accessible despite everyone else on the team being able to access the same domain, either by HTTP or SSH.
