On the evening of October 19, 2015, because the company needed a set of internal testing Juno cloud platform for a visit by national leaders on October 28th, it needed to modify a domain name mapping and assign public network IP. Before that, a set of Icehouse cloud platform had assigned all public network IP segments, but five IP were not used, so I assigned IP to the test Juno platform, and then there was an IP conflict. Before, there was a person who didn't tell me about my IP use, which made his application unavailable. Even if I released the IP address on the Openstack management interface, the Ping passed, using the command line on the Juno cloud platform, as follows:

[root@controller01 ~ (keystone_admin)] # neutron floatingip-list

+-+

| | id | fixed_ip_address | floating_ip_address | port_id | |

+-+

| | e21eb03a-cbad-4e71-9a1f-8150847b3713 | 192.168.0.5 | 124.98.35.115 | 0c06b2f8-8cbf-4ee3-8f78-23a9178d011f |

Check that the 124.98.35.116 address has been released, and the IP address cannot be reached by ping in the public network. Even if we turn off the soft Router and Delete all the public network parts, the developer suspects that someone else is occupying the IP. Then I use the following command:

[root@controller01 ~ (keystone_admin)] # arp-a | grep 124

? (124.98.35.115) at fa:16:3e:ab:c8:e4 [ether] on br-ex

? (124.98.35.116) at fa:16:3e:ab:c8:e4 [ether] on br-ex

? (124.98.35.117) at 00:e0:4e:01:a8:a4 [ether] on br-ex

? (124.98.35.118) at 00:24:c4:50:0b:db [ether] on br-ex

It is found that 124.98.35.116 has not been released, indicating that there is still a problem with Neutron. FloatingIP has not been completely released. You need to use the following to release IP:

[root@controller01 ~ (keystone_admin)] # arp-d 124.98.35.116

[root@controller01 ~ (keystone_admin)] # arp-a | grep 124

? (124.98.35.115) at fa:16:3e:ab:c8:e4 [ether] on br-ex

? (124.98.35.116) at [ether] on br-ex-this is the only way to release

? (124.98.35.117) at 00:e0:4e:01:a8:a4 [ether] on br-ex

? (124.98.35.118) at 00:24:c4:50:0b:db [ether] on br-ex

The above are the problems I have encountered. I hope to help people who have the same problems as I do. Thank you!
