What can a manually entered IP address affect?

Question

Computer networks

1. If you register yourself an ip address manually (see the screenshot. The ip adress field), then regardless of this, when you connect to the Internet, your ip address will still be different? That is, the sites will see a different ip address that the provider gave you?
2. Does your ISP assign you different IP addresses each time you connect to the Internet?
3. What can be affected by a manually entered ip address (the one in the screenshot) in relation to connecting to the Internet through an ISP?

Answer 1

1. The ip-address will not be different, but the one you registered. sites will see the first external address in the chain of routers from you to the ISP.
2. depends on the tariff and the provider. in some cases every time, in others not every time, in others it never changes.
3. whether the Internet will work or not.

Answer 2

If you manually enter an ip address for yourself (see the screenshot. The ip adress field), then regardless of this, when you connect to the Internet, your ip address will still be different?

No. It will be exactly as written. If it's spelled correctly. What address to prescribe - usually agreed with the provider, unless of course you are not a PI.
Sites will see exactly the address from which you access the Internet. If it's spelled correctly. The address on the screen is non-existent. In accordance with RFC1918, it makes no sense to use such addresses to access the Internet.
Depends on the terms of the contract with the provider. Maybe yes. Maybe not (for example, I don't :) )
The one on the screen - no matter what. With such an address simply will not work :) In general - for performance. It will only work with the address given by the provider, because packets from another address on the given port of the provider will simply be ignored.

Answer 3

1. see pre answers.
It looks like you are using an ISP. under this condition, if this IP is registered correctly, you will have the Internet, it will not be wrong.
> That is, the sites will see a different ip address that the provider gave you?
Again, based on the previous assumptions, yes, while accessing the Internet, if the Internet works with such an IP, then yes, the provider gives you a different address (from the available pool). Yes, sites will see a different address.
2. Does your ISP assign you different IP addresses each time you connect to the Internet?
Depends on what the provider wanted when they set up their equipment. It can produce the same, it can produce different, etc. etc.
3. What can be affected by a manually entered ip address (the one in the screenshot) in relation to connecting to the Internet through an ISP?
Is there internet or not? Even purely theoretically, you can try to cheat with IP + mac address and try to introduce yourself as another client, but for this you need to at least know exactly how everything is arranged in Provo, and even then it’s not a fact that everything will pass even theoretically.
