Private IP Address. You can use any private IP address range within your private network. A private network can use both IPv4 and IPv6 addresses. Private IP ranges are NOT allocated to any particular organization. Private IP Ranges specified by RFC 1918 Class A: 10.x.x.x - 10.255.255.255 (CIDR - 10.0.0.0/8),255.0.0.0, 24 bit block
Jan 17, 2023 at 4:22. If you must go back internet-centuries, to a time long before you were born (probably), yes, the three blocks defined in RFC1918 ("Private" addresses), are each Class A (/8), Class B (/16), and Class C (/24) subnets. 10/8 is the only one from the Class A block, because (a) who needs more space, and (b) address space is ...
100.64.0.0 this ip belongs to class A ip address. There are some range of private ip address for each class of ip address. For class A private ip range is 10.0.0.0/8. So if you want a private ip from class A then that belongs to 10.x.x.x ip segment. You cant allocate 100.64.0.0 ip address as a private ip.
I thought 255.255.0.0 was the default/natural mask of a class C private? I have some understanding that CIDR is different from classful. In this example, however, my professor went on to subnet the networks, separating them by 192.168.10.0 and 192.168.20.0 which made no sense to me considering the original question was written with /24.
This will allow you to use any private IP between 192.168.0.1 and 192.168.0.254. Give your router an IP of 192.168.0.1 and ensure everything on the network uses the subnet mask 255.255.255.0. More difficult option: Pick whatever address you want, but increase the /24 value to reduce the number of available IP addresses to match what you ...
15. Why are there three separate ranges of private IPv4 addresses of different sizes? Why not just reserve the largest (10.0.0.0 - 10.255.255.255) range and let people create /16 or /24 (or whatever) networks within that range if they need smaller networks or need to do subnetting? Is there anything wrong with having a huge number of available ...
Most often, IP address and prefix length aka network mask are assigned by a DHCP server. [edit] Who decides whether the ip would be 10.x.x.x or 192.x.x.x. Your network admin does and your DHCP server distributes these addresses. And why are there different types of private ip. The IETF decided to allocate a range for each (former) class for ...
1. When it comes to local networks, you have the freedom to use any IP address you want for your network since it doesn't need to communicate on the internet with other devices. However, the RFC specified a range for private IP addresses (such as 10.x.x.x and 192.168.0-255.x).
As others have pointed out, RFC1918 defines 3 private IP ranges. In 1996, there was still legacy equipment around that didn't support CIDR, so one range was created for each class. Class B addresses start at 128.0.0.0, and class C addresses start at 192.0.0.0; 168 was chosen just because it was unallocated.
An example: Your PC has the private IP address 192.168.2.3 and is connected to an internet router that has the public IP 54.239.25.200. Now, if you open the port 80 in the router then anyone in the public internet could connect to your PC using the URL. The public internet doesn't know your private IP, they know your public IP address.
