Jenkins - Identify IP Addresses of nodes

While doing some research I found several posts on stackoverflow asking how to identify the IP address of nodes.  You might want to know this if you read the decrypting credentials post and managed to get yourself some ssh keys for nodes but you cant actually see the node's IP in the Jenkins UI.

Stackoverflow link: https://stackoverflow.com/questions/14930329/finding-ip-of-a-jenkins-node
blog on setting up a node: https://embeddedartistry.com/blog/2017/12/22/jenkins-configuring-a-linux-slave-node

 There are great answers in the stackoverflow post on using the script console but in the event you found yourself with just the Jenkins directory or no access to the script console it's pretty easy to get this information.

You can just browse to jenkins-ip/computer/$nodename/config.xml. This request will require the extended read permission.

Optionally if you are on the box  or have a backup you can go to jenkins-dir/nodes/$nodename/config.xml
