This page contains historical information. It may be outdated or unreliable.
The nova cli command can be used to examine and alter many settings related to a particular Cloud VPS project or the entire OpenStack cluster. These commands are typically run on the cloudcontrol* hosts (e.g. cloudcontrol1003.wikimedia.org).

List floating IPs
$ nova --os-project-id project-proxy floating-ip-list
+----+----------------+--------------------------------------+-------------+------+
| Id | IP | Server Id | Fixed IP | Pool |

Move a floating IP from one instance to another
Example and discussion here: Moving a floating IP for the Web Proxies in toolforge
Essentially, run:
$ OS_TENANT_NAME=project-proxy openstack ip floating remove 208.80.155.156 <current instance UUID>
$ OS_TENANT_NAME=project-proxy openstack ip floating add 208.80.155.156 9930528e-c824-48e0-932e-862ffe582412
You do really should remove the ip from its prior instance. The backend system may not take care of that automatically per phab:T143639#3116120.
