An IP address is defined by Internet Protocol version 4 as a 32-bit binary number. Theoretically, there are about 4 billion (2 to the power of 32) IP addresses available for us, which seems like a large IP address space. According to the different network ID and host ID number rules, IP address can be divided into three categories, including A (7 network ID and 24 host ID), B (14 network ID and 16 host ID), and C (21 network ID and eight host ID). Due to the development of the Internet and improper distribution, IPv4 addresses was exhausted at the IANA level.
So, the IP address resource is very precious. The majority of users are using dynamic IP addresses. They get access to the Internet via ADSL, ISDN, wired broadband, Modem, community broadband and so on. Each time, they will get a temporary allocation of IP addresses.
What are dynamic IP addresses?
A dynamic IP user needs to obtain an IP address when connecting to the Internet each time. Dynamic IP addresses can be different every time you connect to the Internet. Dynamic IP addresses are obtained from the Dynamic Host Configuration Protocol (DHCP) servers. It assigns dynamic IP addresses, subnet masks, default gateways, and DNS servers to devices.
You don’t need any configuration to use dynamic IP addresses. Besides, it doesn’t cost you extra money to use a dynamic IP address. Since dynamic IP addresses change frequently, they are also more secure than static IP addresses. After all, moving targets are harder to hit than stationary ones.
What are static IP addresses?
A static IP address is distributed by the ISP and a static IP user can connect to the Internet without obtaining an IP address. And you will use the same address every time you connect to the Internet. An organization that has set up an Internet service should publish a static IP address so that users can get access to its services. Of course, digital IP is difficult to remember and recognize, people are more accustomed to accessing the host via the domain name. Actually, when a user enters a URL in a browser, the domain name server (DNS) transfers the domain name into the IP address.
Static IP addresses, as well as dynamic addresses, have no impact on your Internet speed. They are IP addresses that are permanently assigned to devices. With a static IP address, you can connect to the Internet directly without dial-up.
Dynamic IP Addresses vs. Static IP Addresses
Dynamic IP addresses are good enough for most Internet users. This type of IP address is free of charge and easy to use. A dynamic IP address also prevents you from being an easy target to hackers because it changes frequently.
Since Internet users are widely spread in the world and the time that they surf the Internet is not fixed, it would cause a great wast of IP address resources if each user is assigned a static IP. The Internet service provider (ISP) will give you a dynamic IP address because dynamic IP addresses are more cost-effective than static IP addresses.
However, if you want a static IP address that is assigned to you permanently, you can spend extra money on applying for one. Both dynamic IP addresses and static IP addresses are very essential to the Internet and its users because they work together to make it easier to manage networks.
How to prevent IP address leaks?
There are many potential risks on the Internet, which includes IP address leaks. An IP address to your computer is a street number to your house. Others can keep a track of you online via your IP address. It is a good idea to protect yourself from an IP address leak with a VPN. Here we’d like to introduce RitaVPN to you. It will secure your IP as you wish.
