IPv4 subnet mask is 32 bits large. In a valid subnet mask network part is represented with "1" from left side followed and ended by host part "0" - 11111111.11111111.11111111.00000000 (binary form), 255.255.255.0 (dotted-decimal form) or simply "/24" (where 24 represents that subnet …
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 E. IP address: 192.168.20.30 Subnet Mask: 255.255.255.240 Default Gateway: 192.168.20.25 *Answer: C. You are working in a data center environment and are assigned the address range 10.188.31.0/23. You are asked to develop an IP addressing plan to allow the maximum number of subnets with as many as 30 hosts each.Which IP address range meets

This appendix includes the following sections: • Uses for Subnet Information • Addresses in the .128 Mask • Addresses in the .192 Mask • Addresses in the .224 Mask • Addresses in the .240 Mask • Addresses in the .248 Mask • Addresses in the .252 Mask The subnet masks are also identified by the number of bits in the mask. lists subnet masks by the number of bits in the network ID. Subnet masks (IPv4) and prefixes (IPv6) In IPv4, the subnet mask 255.255.255.0 is 32 bits and consists of four 8-bit octets. The address: 10.10.10.0 subnet mask 255.255.255.0 means that the subnet is a range of IP addresses from 10.10.10.0 - 10.10.10.255. The prefix-length in IPv6 is the equivalent of the subnet mask in IPv4. Subnetting - Calculate Subnet Masks & More | Pluralsight
In IPv6, the network prefix performs a similar function as the subnet mask in IPv4, with the prefix length representing the number of bits in the address. Prior to the introduction of CIDR, IPv4 network prefixes could be directly obtained from the IP address based on the class (A, B, or C, which vary based on the range of IP addresses they
