My IP keeps changing?

Yesterday i was on my server and all of the sudden i get kicked. I looked and notcied that my internet waS down. SO i restarted everything and i try to go on my server and it cant connect. I look in the console ans saw that my listen IP changed. So i just reforwarded the ports to the new IP. So just now i get on and see that the IP changed AGAIN. Why does it keep changing? This has never happened before! Help me!

 

get a domain and no-ip
you can create a free domain with no-ip and a program that registrers if your ip changes and points the new domain to your new ip
also you can point the other domain to the no-ip domain

 

Ok, so you go to no-ip.org , sign up, download the program, and setup the DNS. It automagically adapts to your IP.

 

I already do have a custom domain.
Could this be caused by making another server on a different computer?

 

point the doomain to the no-ip domain and keep the no ip program running on the server computer

then the no-ip domain always point to your ip and your custom domain always point to the no-ip domain

Yesterday I unplugged my modem...Is that why it changed?

 

What the other guy is saying is completely not true!

The IP of your computer keeps changing because your router assigns a certain IP to your computer. You can set a dedicated IP on your router to the computer.

Also, when you unplug your modem, your public IP can change, make sure to avoid doing that.

 

I unplugged my modem once and it changed the IP. It stayed plugged in and it changed yet again. Can you please help me solve this?

 

CC3475 Try this: http://corz.org/comms/hardware/router/static.ip.address.php?page=all#static-ip-notes

 

Do you have a Static IP?

 

i have a dynamic ip

Its not the IP for the server, its my IPv4 address

If it is the last few numbers that keep changing you need a static IP, I had the same issue.

 

Or he may have a short DCHP lease. What modem brand do you have? What model as well?

 

*DHCP
But yea, that might also be the problem.
Looking at this, I think he just doesn't have a static IP, which he needs. The router will 'remember' your MAC address and assign a certain IP to it every time he sees it.

 

Mine actually doesn't do that. (A NetGear) -- I don't host any servers from my house, but my IP is dynamic externally, as well as internally.
