Internal IP address
An Internal IP address is a number that identifies your network device, and is provided by your router. The router manages data packets in and out of your network. Think of it like the receptionist at a company. The internal IP address protects you and your data. It’s important to note that your internal IP address will change periodically, and that your ISP can change it at any time.
You can check whether your internal IP address is private or public by searching for the word “private” or “IPv4” at the end of your address. You can also use a proxy server if you’re concerned about privacy. In general, your ISP can track your internal IP address if it’s linked to your modem.
Public IP address
A public IP address is a unique identifier that identifies a device on the internet. It is assigned by your ISP and can be static or dynamic. This address can contain information about you, including websites that you visit and your ISP. This information can be misused by advertisers, governments, and other third parties to monitor your activities.
When you use a public IP address, you expose yourself to cyberattacks and other threats. You can’t protect your information with this type of address, because malicious websites can trace your IP address back to your device. Plus, your ISP is powerless to stop these attacks if your IP address is public.
Static IP address
Static IP addresses are a way of referencing a particular device on the internet. This https://iosj.io/ allows uninterrupted data transfer, whereas dynamic IP addresses might cause hiccups. For this reason, businesses should consider getting a static IP address for all of their devices. This can be used in many different situations, including a website, email, networked printers, and virtual private networks. Here are some of the benefits of static IP addresses.
Static IP addresses are easier to remember. This makes them more convenient for advanced networking tasks. Also, they are much more stable, making them better for voice over IP, games, and VPNs. However, a disadvantage of a static IP address is that it requires you to manually configure all connected devices. This can be a time-consuming and expensive process.
Classful network design
IP addresses are classified into two categories: classes A and B. Class A addresses are reserved for use by public organizations. Class B addresses are reserved for testing purposes and class E addresses are reserved for special use. The class “A” IP address range is very small. Thus, it’s unlikely that a company or an individual will be able to obtain it.
Class C addresses, on the other hand, must have a common prefix, which must be a power of two. Thus, class C addresses are best suited for organizations that have fewer than 255 hosts.
