Is IPv4 a private IP address?

Summary of the Article:

The article discusses the differences between public and private IP addresses, specifically focusing on IPv4 addresses. It explains that according to the standards set by the Internet Engineering Task Force (IETF), certain IPv4 address ranges are reserved for private internets and are not publicly routable on the global internet. The article also states that a public IP address is reachable from the internet, while a private IP address is used within a private network to connect securely to other devices within the same network. It further provides information on how to determine if an IPv4 address is public or private, as well as the ranges of private IPv4 addresses. Additionally, the article briefly mentions IPv6 and its similarities to IPv4 in terms of private address ranges.

Questions and Detailed Answers:

6. What is the difference between a public IPv4 address and a private IPv4 address?
A public IPv4 address identifies you to the wider internet so that all the information you’re searching for can find you. On the other hand, a private IPv4 address is used within a private network to connect securely to other devices within the same network.

Yes, 172.99.1.1 is a private IPv4 address. Private addresses are assigned to devices within an organization’s intranet (internal network), and internet routers will typically forward any packet with a destination address that is a private IPv4 address.

10. Which three IPv4 addresses are private?
The three ranges of private IPv4 addresses are:
– Class A: 10.0.0.0 to 10.255.255.255
– Class B: 172.16.0.0 to 172.31.255.255
– Class C: 192.168.0.0 to 192.168.255.255

11. Is 172.0.0.0.1 a public or private IP address?

Why we use IPv4 instead of IPv6

There is a routing protocol that is supported by the routed daemon in the case of IPv4. As a result, IPv4 is preferred over IPv6 in terms of routing performance. Since IPv6 lacks particular routing protocol support, it relies solely on static routes. As a result, it is less popular than IPv4.

Why is IPv4 still used rather than IPv6

The main reason IPv4 is still more widely used than IPv6 is because it takes a lot of time and resources for the transition from one to the other.
