Perfectly valid, your subnet range is: 192.168.5.0 -> 192.168.5.255. 192.168.5.0 and 192.168.5.255 are in the subnet but are not valid address, the first is the network address and the 2nd is the broadcast address. – Richard Critten Aug 13 '16 at 21:37
A subnet is division of an IP network (internet protocol suite), where an IP network is a set of communications protocols used on the Internet and other similar networks. It is commonly known as TCP/IP (Transmission Control Protocol/Internet Protocol). If a subnet doesn't have a route to the internet gateway, but has its traffic routed to a virtual private gateway for a Site-to-Site VPN connection, the subnet is known as a VPN-only subnet. In this diagram, subnet 3 is a VPN-only subnet. Oct 09, 2019 · Subnets, hosts and broadcast addresses per subnet: To find the valid subnets for this specific subnet mask you have to subtract 248 from the value 256 (256-248=8), which is the first available subnet address. Actually the first available one is the subnet-zero which we explicitly note. Mar 12, 2014 · Traditionally, the subnet itself must not be used as an address. If we use more bits out of the host space for networking, we can get more and more subnetworks. CIDR Notation. A system called Classless Inter-Domain Routing, or CIDR, was developed as an alternative to traditional subnetting. The idea is that you can add a specification in the IP
Perfectly valid, your subnet range is: 192.168.5.0 -> 192.168.5.255. 192.168.5.0 and 192.168.5.255 are in the subnet but are not valid address, the first is the network address and the 2nd is the broadcast address. – Richard Critten Aug 13 '16 at 21:37 Jun 25, 2020 · We are looking at adding more IP addresses, so the solution was suggested of expanding the subnet mask to /23. Thus, our subnet mask would be 255.255.254.0. Hypothetically, we were told our range of valid IP addresses would now extend from 192.168.8.1 to 192.168.9.255.
ABOUT SUBNET CALCULATOR. The subnet calculator lets you enter a subnet range (CIDR) and see IP address information about that range You can type your range directly in CIDR notation, or use the optional Mask pull-down: 74.125.227.0/29; 74.125.227.0, then select Optional Mask from dropdown
Using 0 as an address only seems crazy if your thinking about /24 or smaller address space (/31 & /32 aside) if you work with /23 or bigger address apace 0 becomes an entirely valid and normal address to use as the Subnet Boundaries beging with /23 will span multiple octets so if you left 0 out you would be wasting a lot of addresses very quickly
