What are the 5 IP classes?

With an IPv4 IP address, there are five classes of available IP ranges: Class A, Class B, Class C, Class D and Class E, while only A, B, and C are commonly used. Each class allows for a range of valid IP addresses, shown in the following table.

What are the private IP address classes?

Private Address Ranges

• 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.

What are the 3 private IP address ranges?

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)

Is 192.168 private or public?

private IP address
And don’t be surprised if you have a device or two at home with a so-called 192 IP address, or a private IP address beginning with 192.168. This is the most common default private IP address format assigned to network routers around the globe.

What is private Class C IP?

Reservation of IP addresses in Class C networks Networks belongs to “Class C” from 192.168. 0.0 to 192.168. 255.0 are reserved for private use and can be used inside any organization. Computers which are not connected directly to the Internet do not need globally-unique IPv4 addresses.

What class is a 172 IP address?

class B address
The address 172.16. 52.63 is a class B address. Its first octet is 172, which is between 128 and 191, inclusive.

What are the private subnets?

Instances in the private subnet are back-end servers that don’t need to accept incoming traffic from the internet and therefore do not have public IP addresses; however, they can send requests to the internet using the NAT gateway (see the next bullet).

What is a Class C private IP address?

Class C addresses are used in small local area networks (LANs). Class C allows for approximately 2 million networks by using the first three octets for the network ID. In a class C IP address, the first three bits of the first octet are always 1 1 0.

What is my private IP?

What is a 172.16 IP address?

Private IPv4 addresses

RFC 1918 name	IP address range	Classful description
24-bit block	10.0.0.0 – 10.255.255.255	single class A network
20-bit block	172.16.0.0 – 172.31.255.255	16 contiguous class B networks
16-bit block	192.168.0.0 – 192.168.255.255	256 contiguous class C networks

Is 172 public or private IP?

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.

How do you identify a private subnet?

So, to determine if a given subnet is public or private, you need to describe the route table that is associated with that subnet. That will tell you the routes and you can test for a 0.0. 0.0/0 route with a gateway ID of igw-xxxxxxxxxxxxxxxxx (as opposed to local ). Here, you can see a destination route of 0.0.

What is my subnet mask?

On Windows Go to Control Panel > Network and Sharing Centre. Click on your network name and then click Details. You will find the subnet mask along with other network details.
