Usage of 192. 168. xxx, 172. xxx and 10. xxx in private networks The deal is that everything else, with the exception of a few other restricted subnets (such as multicast, localhost, APIPA, etc ) are routable on the internet, so if you decide to use something other than 192 168 0 0 16, 172 16 0 0 12, or 10 0 0 0 8 privately (in an IPv4 network), such as 100 200 0 0 16, keep in mind that you will not be able
What range of IP addresses is represented by the CIDR block 172. 16. 0. 0 12? I would have put 1010 1100 representing 172 " You are right and the solution sheet is wrong Probably just a typo on the part of whoever wrote the solution sheet also don't understand how the block represents the IP addresses from 172 16 0 0 to 172 31 255 255 1010 1100 0001 0000 0000 0000 0000 0000 is 172 16 0 0
Overlaps with VLANS - Network Engineering Stack Exchange Your int vlan 3 IP address falls in a subnetwork of 172 16 0 128 27 with possible host range of 172 16 0 129-172 16 0 159 It definetely overlapps with int vlan 2 IP address you've assigned Share
How to tell if an ipv4 address is public or private? I've read the below thing, in a website According to standards set forth in Internet Engineering Task Force (IETF) document RFC-1918 , the following IPv4 address ranges are reserved by the IANA for
How to divide an IPv4 network into subnets of different sizes as . . . You could use 172 16 0 128 25 and then 172 16 1 0 25 for the next I like to avoid zero subnets though, but it is a valid range If you do the math you would see that the network address for 172 16 0 8 25 is actually 172 16 0 0 If you need 100 hosts and want to use a 25 subnet then you would have to start at 172 16 0 0 and count increments of
What is a routable IP? - Network Engineering Stack Exchange use , along with (172 16 0 0) and (10 0 0 0) ranges so when you see those ranges you should know you are in a private network Dynamic IP changes every time you router rebooted So people can't access your website what You need is an static IP , which will remain the same Static IP comes with extra charge , you can discuss the cost
Why is my Routers WAN IP different from public IP? Also, using 172 100 creates a risk of these routes being leaked into the global BGP table This is speculation, but since your WAN IP starts with 172, someone could be assuming the whole 172 0 0 0 8 range is private (but actually only 172 16 0 0 12 is private) Otherwise, someone is knowingly squatting IP space
