Verifying server ownership doesn't work?

Please, before setting up a server you should read the manual.

Paragraph 7

IP address notes
Unless you set a static IP for the computer that is hosting the game, the internal IP address can change. This affects port forwarding rules, and can make them invalid. Each modem or router has a different way of setting a static IP address. You should refer to the manual for your device(s) or online documentation for further instruction.
If you are having players connect to your external IP, your external IP can change if you do not have a static IP from your internet service provider. Use a tool such as MyWANIP to periodically check on the external IP address. You may also search "my ip address" on Google and it will show your IP address. Alternatively, you can look into a DNS service that will allow you to have a name, rather than an IP address, that will remain the same. The name will point to your external IP address, regardless of whether or not it changes (the DNS is updated when changes occur).
Firewalling, NATs and external IP addresses
You must open the TCP port (default is 25565) on the firewall.
If the server in question is not reachable via a globally routable IP address, you will need to add appropriate address and/or port number translation rules to the gateway — usually your router has the global IP address.
For help with address translation, opening the firewall and routing (these three make up what people call port mapping/forwarding), portforward.com is a good source. Select your router from that list, skip the ad that comes after selecting the device, and you will see instructions for setting up port forwarding. Alternatively, you can read the documentation supplied with your router, modem, or other ISP related hardware.
Verify the port is open, and note your external IP by using a port checker tool, such as You Get Signal. The default port you should test is 25565, unless you specified something else. Have the Minecraft server running when you test the port.
You can obtain your external IP address from YouGetSignal.

I hope I helped.

That is an internal IP address. PMC needs your external IP address when verifying. You can get this by going to google and type in "What is my IP address"

To verify ur server and let other people join without hamachi yes

Even if I can already connect to my server I need to do this?

You are using you're Gateway. Before other people or planetminecraft can reach ur server you need to portforward 25565.
After that you need to know ur IP http://whatismyipaddress.com/
IP Information: xxxxxxxxxxx
Fill in that IP in your minecraft client and see if you can connect. if you can then its also possible to verify your server ownership.

Because that's your ip to your computer that the router assigns to the computer on the network.
