On the contrary, classless addressing can set the network boundary practically anywhere, thus breaking the classful limitations.Sat, 18 Apr 2026 13:19:00 GMThttps://learningnetwork.cisco.com/s/question/0D53i00000KstP1CAJ/ch14-qn-1-from-ccent-book-by-wendell-odom-pg-370When thinking about an IP address using classful addressing rules, an address can have three parts: network, subnet, and host. If you examined all the addresses in one subnet, in binary, which of the following answers correctly stastes which of the three parts of the addresses will be equal among all addresses a) network part only b) subnet ...Wed, 29 Oct 2025 05:36:00 GMThttps://learningnetwork.cisco.com/s/question/0D53i00000KsuyGCAR/classless-and-classful-addressingBefore subnetting, in a classful address, between the 1's and the 0's you can have another part of subnet bits of 1's, hence 3 parts. After subnetting, that is classless addressing, all the 1's combined (network bits +subnet bits) represent one single network and the zero's the host part/bits. So you have two parts. Just thinking out loud here.Fri, 17 Apr 2026 17:16:00 GMThttps://learningnetwork.cisco.com/s/binary-gameHave some fun while you learn and reinforce your networking knowledge with our PC Game on the Cisco Learning Network.

You must have in count the following considerations: Classless and Classful addressing Classless and Classful routing Now, in a device, we see the routing table Even if you work with a routing protocol as EIGRP (classless routing protocol), the Classful addressing is referenced as "base" because in this Classful network (10.0.0.0/8) was applied VLSM and you can see different subnets with ...Fri, 17 Apr 2026 05:14:00 GMThttps://learningnetwork.cisco.com/s/article/classless-ip-addressingClassful Addressing: All the classes of IP address such that A, B, and C comes in Classful. I mean /8 in case of Class A, /16 in case of Class B and /24 in case of Class C are classful. We can't change it and we use it in these prefix lenghts. Classless Addressing: All IP addresses other then the above prefix lenghts are called classless.Thu, 02 Apr 2026 17:06:00 GMThttps://learningnetwork.cisco.com/s/question/0D53i00000Kt0GmCAJ/cidr-and-address-classesThe 172.16.0.0 to 172.31.255.255 range, however, is still considered a classful B address range. 10.0.0.0 is the class A private address range, and 192.168.0.0 is the class C address range. The way I think of it, it's important to know what the classful ranges are, even though we use classless subnets.Sat, 18 Apr 2026 10:27:00 GMThttps://learningnetwork.cisco.com/s/question/0D53i00000Ksv3rCAB/classful-vs-classlessThat means 65534-2000 = 63534 IP address wasted. While using classful addressing, that is the only choice made available to you. So to effectively solve this problem of waste of IP address, classless addressing is implemented, where you would be assigned a mask/prefix according to your requirements providing flexibility, a fluid design.Wed, 01 Apr 2026 06:37:00 GMThttps://learningnetwork.cisco.com/s/Get valuable IT training resources for all Cisco certifications.
