Summary:
The article discusses the differences between public and private IPv4 addresses. It explains that public IP addresses are used to identify devices on the wider internet, while private IP addresses are used within a private network. It also mentions that both IPv4 and IPv6 have private IP address ranges that can be used by anyone without approval from internet registries. The article provides the specific class configurations for private IPv4 addresses, such as Class A (10.x.x.x), Class B (172.16.x.x to 172.31.x.x), and Class C (192.168.x.x). It confirms that 172.99.1.1 is a private IPv4 address and describes what public IPv4 addresses look like. The article also provides a list of public IP address ranges. It concludes by mentioning that IPv6 is more secure than IPv4 when implemented correctly, thanks to IP Security (IPSec) protocols.

8. IPv6 is considered more secure than IPv4 when implemented correctly.
9. IPv6 uses IP Security (IPSec) protocols to promote authentication, security, and data integrity.
10. Yes, anyone can use private IP addresses without approval from regional or local internet registries.
How do I know if my IPv4 address is public or private
The way to tell is to reference a standard used by TCP/IP:An IPv4 address beginning with any of the following is a private address: 172.16., 172.17., 172.18, etc up to 172.30. and 172.31. 192.168.Otherwise it's a public IPv4 address (with a few minor exceptions)
What is public IPv4 vs private IPv4
A public IP address identifies you to the wider internet so that all the information you're searching for can find you. A private IP address is used within a private network to connect securely to other devices within that same network.

Is IPv6 public or private
Both the IPv4 and the IPv6 specifications define private IP address ranges. Private network addresses are not allocated to any specific organization. Anyone may use these addresses without approval from regional or local Internet registries.

Is IPv4 secure
This makes IPv6 secure as encryption scrambles the content of your internet traffic so that anyone intercepting is unable to decipher it. However, IPSec can also be implemented on IPv4, which means that, in theory at least, IPv4 has the potential to be just as safe as IPv6.
Is IPv4 a security risk
Security risks of IPv4
Sniffing is when an attacker intercepts and reads the data packets sent or received by a device on a network, which can be used to steal sensitive information. Fragmentation is when a packet is divided into smaller pieces to fit the maximum transmission unit (MTU) of a network.

Is it bad if someone knows my IPv4
Your IP address is essential for sending and receiving information online. But if a hacker knows your IP address, they can use it to seize valuable information about you. Using it as a starting point in a broader attack, they could hack your device or intercept your online traffic, just for starters.
Can IPv4 address be tracked
To clarify, it does not reveal your location. If someone was able to get your IP address they could learn a bit about your Internet service, such as which provider you use to connect to the Internet, but they really can't locate you, your home, or your office.
Does IPv4 have built in security
Lack of security: IPv4 doesn't have in-built security features. Network security wasn't even a concern back in the day. You can configure IPSec — a set of protocols to authenticate and encrypt data over IPv4 — to secure your traffic.
