The subnet calculator allows the use of a single subnet bit - for example, a class C address with a subnet mask of 255.255.255.128 is permitted. The subnet calculator allows a subnet ID to have its final octet equal to the final octet of its subnet mask - for example, a class C network address of 192.168.0.192 with a subnet mask of 255.255.255

2-4 Variable Length Subnet Masks (VLSM) - Free CCNA Study VLSM allows you to use different subnet masks across the network for the same class of addresses. For example, a /30 subnet mask, which gives 2 host addresses per subnet, can be used for point-to-point links between routers. Figure 2-2 shows how VLSM can be used to save address space in the network shown in Figure 2-1. Set up 4 ip addresses with Subnet mask 255.255.255.252 (30) /30 network gives you only two useable IP addresses (other two are network and broadcast) and one of them is the gateway, so essentially they gave you one static IP address which is 84.84.185.177. Assign this address to your interface, set network mask to 255.255.255.252, set your default gateway to 84.84.185.178 and it should work. CCNA Subnetting Flashcards | Quizlet

These are /24, /30, /31/ and /32. • /24 is the Subnet Mask that is usually used in the local networks by default. • /32 is the Subnet Mask used generally on Loopback and System interfaces. • /31 is the Subnet Mask used on point-to-point links. • /30 is also widely used in Service Provider Networks for Subnetting Reference Sheet
