What are the 3 ranges of private IP addresses?

The Internet Assigned Numbers Authority (IANA) has reserved the following three blocks of the IP address space for private internets:

• 10.0. 0.0 – 10.255. 255.255 (10.0. 0.0/8 prefix)
• 172.16. 0.0 – 172.31. 255.255 (172.16. 0.0/12 prefix)
• 192.168. 0.0 – 192.168. 255.255 (192.168. 0.0/16 prefix)

What is the private range of IP addresses?

Summarizing the differences between private and public IP addresses

Are all 172 IP addresses private?

Note that only a portion of the “172” and the “192” address ranges are designated for private use. The remaining addresses are considered “public,” and thus are routable on the global Internet. x.x.x IP address may have difficulty reaching some sites on the global Internet.

What is the best private IP address range?

One thing I would suggest is to use randomly selected private ranges from the 10.0. 0.0/8 block for all of your private addresses. This avoids lots of problems, particularly when setting up VPNs between home/partner networks and your corporate network. Most home routers (and many corporate setups) use 192.168.

Is 172.16 a private IP?

The 172.16. 0.0/12 private network can be interpreted either as a block of 16 class B network IDs or as a 20-bit assignable address space (20 host bits) that can be used for any sub-netting scheme within the private organization. 0.0/12 private network allows the following range of valid IP addresses: 172.16.

How do I know if my IP is public?

To check if your IP address is public, you can use myip.com (or any similar service). You will be shown the IP address that was used for accessing the site; and if it matches the IP address that your Internet service provider assigned you, then you have a public IP address.

What are the ranges of private IP addresses?

Private IP Address Ranges 1 10.0.0.0 to 10.255.255.255 2 172.16.0.0 to 172.31.255.255 3 192.168.0.0 to 192.168.255.255 More

Are there any restrictions on IPv4 private address space?

There have been reports from the community that many network operators are denying access to devices having IP addresses from within the entire 172 /8 range. As a result, any device with a 172.x.x.x IP address may have difficulty reaching some sites on the global Internet.

Can a private IP address be used on the Internet?

There are three ranges of addresses that can be used in a private network (e.g. your home LAN or office) Internet routers are configured to discard any packets coming from the private IP address ranges, so these addresses are not routable on the Internet.

Why are private IP addresses not globally unique?

Because private IP addresses are not globally unique, both organizations can use private IP addresses from the same range. To access the Internet, the organizations can use a technology called Network Address Translation (NAT), which we will describe in the later lessons.
