If I have a static ip, is it public and public?

Question

Computer networks

Is my home ip address public? If rebooting the router ip does not change, then it is static?
Let's say if I open port 443 or 8080 in the router and on my PC, will the ports be available for external connections so that I can host a website or some other applications on them?

Answer 1

static can be gray.
dynamic can be white.
So it goes.
if you can’t find out from the provider, then just look at the ranges of gray networks and compare with your address.

Answer 2

It is impossible to give an unambiguous answer to this question.
You can have a static and globally routable address, but the provider, for example, can cut incoming connections on a number of ports like 22, 80, 443.
Maybe not.
Maybe you have a provider natit in CGNAT at one address thousands of subscribers.
The question definitely needs clarification.

Answer 3

write the address here - they will answer you

Answer 4

Hello.
Whatever your IP is, eventually surf the Internet through a PUBLIC (public - "white", "public", "global", "external") IP address.
For the roughest definition, if you are not using a VPN connection, go to, for example, https://whatismyipaddress.com/ . If there under "My IP Address is:" the IP matches what is on your device, then you have a PUBLIC (public) IP address. And if it is different, then with a probability of 99.99999% you have a PRIVATE (private), not routable, not public, not public, "gray" IP address.
All public IP addresses on the Internet are unique and cannot be repeated.
Meanwhile, private ("gray", private) IP addresses can be used many times in many networks, because they are not routable on the Internet and traffic from the Internet cannot be sent to them, they work only within the local network and distribution of such addresses by no one controlled.
List of private ("grey", private) IP addresses:
From 10.0.0.0 to 10.255.255.255
From 172.16.0.0 to 172.31.255.255
From 192.168.0.0 to 192.168.255.255
