What is a Real Ip?
A real IP (Internet Protocol) is a unique numerical identifier that is assigned to every device that is connected to the internet. It is also sometimes referred to as a public IP address.
Real IP addresses are assigned by Internet Service Providers (ISPs) and are used to identify devices on the internet and route data to and from them. Unlike private IP addresses, which are used within local networks and are not publicly visible on the internet, real IP addresses are publicly visible and can be accessed by anyone who knows the address.
Real IP addresses are essential for devices that need to communicate over the internet, such as servers, websites, and other networked devices. Without a real IP address, these devices would not be able to communicate with other devices on the internet.
how to know if i have real ip?
You can determine whether you have a real or public IP address by checking the IP address assigned to your device by your Internet Service Provider (ISP). There are several ways to check your IP address:
Using a search engine: You can simply search for "What is my IP address" in your preferred search engine and it should display your public IP address.
Checking your network settings: On a Windows computer, you can open the Command Prompt and enter the command "ipconfig", which will display your IP address information. On a Mac, you can open the Terminal and enter the command "ifconfig" to display your IP address.
Using an online IP address checker: There are several websites that can display your public IP address, such as WhatIsMyIP.com or IPChicken.com.
Once you have your IP address, you can check whether it is a real or public IP address by verifying that it is not a private IP address. Private IP addresses are typically in the following ranges: 10.0.0.0 to 10.255.255.255, 172.16.0.0 to 172.31.255.255, or 192.168.0.0 to 192.168.255.255. If your IP address falls within one of these ranges, then it is a private IP address, and not a real or public IP address.
how to configure real Ip for home server
Configuring a real IP address for a home server involves several steps:
Check with your Internet Service Provider (ISP) if they provide a static public IP address. Some ISPs provide dynamic public IP addresses that change from time to time, which can make it difficult to access your home server.
Configure your home network to allow incoming traffic to your server. This can typically be done by setting up port forwarding on your router. You will need to forward the relevant ports to your server's private IP address, which is assigned by your router.
Configure your server's firewall to allow incoming traffic on the relevant ports. You can configure the firewall settings to allow incoming traffic on specific ports while blocking other traffic.
Assign a static private IP address to your server. This is important to ensure that the port forwarding configuration on your router is always pointing to the correct IP address.
Set up a dynamic DNS service if your ISP provides a dynamic public IP address. This will allow you to assign a hostname to your home server that will always point to your current public IP address, even if it changes.
It's important to note that configuring a home server with a real IP address can expose your server to the internet and potentially to security risks. Therefore, it is important to ensure that your server is properly secured with up-to-date software and security measures, such as firewalls and access controls.
