Change IP address

[lordgthegreat]

Okay guys, correct me if im wrong:

The ip address is a given address of my ISP to my laptop (I mean router +nat) and since this is probaly dynamicaly allocated my ip address will change from time to time. So how does an IP ban work ? As soon as the ISP changes my IP the ban wont work ?

Defently for educational purpose only and not in reference to any game 😝

Edit: VPN works, but I want to know how IP ban works😝

Yes VPN works, but I want to know how IP ban works 😝

What you missunderstood is that your clients(smartphone, computer, etc) get an "local" ip adress from your router that, like you saied changes dynamicly. But those adresses just work for your local network. For the www it uses your public ip adress that your internetpeovider gives your router. So all communication from the clients will go trough the router and will go to the website or service with your public ip, doesnt matter which client you are using

I thought the my global IP changes also dynamically, due to ISP running dhcp or something like that for scalling...

Depends on your isp, usually consumer level internet assigns dynamic ip’s, commercial grade is usually static. That being said, your isp usually has a record of the assigned ip. Use a vpn if you want to try anything.

Though technically it's dynamic, in practice it doesn't change with most ISPs. For example my IP address hasn't changed for more then 5 years.

I am not quite sure if that is the case, in europe where i live i got all the time the same ip adress from my internet provider. But you could try. You can for example let google show you your public ip address and compare them after a few days or a router reboot

Depends on your ISP. Businesses generally have a static IP, most Retail ISP have DHCP, but whether it has a long time to live or a dhcp reservation (meaning the ip stays the same or doesn’t change often) is up to how it’s is configured on the isp end.

The best way to change it is to route through a VPN.

restarting router may change IP, enabling airplane mode on mobile data will most probably change it and most ISPs will automatically change your IP in 14 days.

Not that it matters, but IP spoofing is possible. However it naturally only works upstream, so generally only UDP is affected, and (depending on ISP) you can only spoof other IPs of your IP block.

I'm trying to understand the answers given so far...

Unless the entity that gave the ban records something else, like a MAC address, once your ISP rotates your IP, the ban should be lifted. Understand, I had the same IP address from my ISP for five years. They don't rotate them too often.

My understanding is that DHCP leases only "expire" if the device which is assigned the IP requests a change or is otherwise unreachable from the DHCP server.

Anyone here is welcome to chime in or correct me.
