Title:
  Unable to list nova instances using "IP" regex filter

Status in OpenStack Neutron (virtual network service):
  New
Status in Python client library for Nova:
  Invalid

Bug description:
  CLI guide of nova list tells that instances can be listed out with IP
  regex filter  -

  [raies@localhost devstack]$ nova help list
  usage: nova list [--reservation-id <reservation-id>] [--ip <ip-regexp>]
                   [--ip6 <ip6-regexp>] [--name <name-regexp>]
                   [--instance-name <name-regexp>] [--status <status>]
                   [--flavor <flavor>] [--image <image>] [--host <hostname>]
                   [--all-tenants [<0|1>]] [--tenant [<tenant>]] [--deleted]
                   [--fields <fields>] [--minimal]

  List active servers.

  Optional arguments:
    --reservation-id <reservation-id>
                                  Only return servers that match reservation-id.
    --ip <ip-regexp>              Search with regular expression match by IP
                                  address.
    --ip6 <ip6-regexp>            Search with regular expression match by IPv6
                                  address.
    --name <name-regexp>          Search with regular expression match by name
    --instance-name <name-regexp>
                                  Search with regular expression match by server
                                  name.
    --status <status>             Search by server status
    --flavor <flavor>             Search by flavor name or ID
    --image <image>               Search by image name or ID
    --host <hostname>             Search servers by hostname to which they are
                                  assigned (Admin only).
    --all-tenants [<0|1>]         Display information from all tenants (Admin
                                  only).
    --tenant [<tenant>]           Display information from single tenant (Admin
                                  only).
    --deleted                     Only display deleted servers (Admin only).
    --fields <fields>             Comma-separated list of fields to display. Use
                                  the show command to see which fields are
                                  available.
    --minimal                     Get only uuid and name.

  I am able to filter instances using their name regex but I am unable to filter with IP regex.
  When I use complete IP only then IP instance of that IP can be listed but regex of IP does not work.

  Steps performed by me are as -

  1.

  This we can see, Instances list with server regex could not found.
