whats the difference between a classless route table and a classful route table ?

Question

if possible show me a classless route table in windows , ive seen the classful one , i just wanna see the classless one , thanks yall

Answer 1

Windows uses classless routing, like almost everything these days. It doesn't have and doesn't need a "classful" route table.



The first part of an IP address represents the network and the rest represents a machine on that network.



"Classful" routing is from the olden days of networking, when networks came in only 3 sizes: Class C, with (almost) 256 addresses, class B with (almost) 256*256 = 65,536 addresses, and Class A, with over 16 million.



You could tell what class a network was by the first number of the IP address.



This was incredibly wasteful, and extremely inflexible, so they decided to do away with classes based on the initial part of the IP address, and allow networks of any size (as a bonus, they could also be subdivided into sub networks). The netmask in your routing table shows where the network part of an address ends and the host part begins. (there is an alternative way to show this, by adding /24 or /8 or some such to the end of address - this shows how many "bits" are in the network part - and the rest are the host part of the address).



That's why your routing table has addresses and netmasks.



This is called classless routing. "Classful" was coined at this point as a name for the old way of doing things.



In old-style "classful" routing, you didn't need a netmask, because you could tell where the network / host boundary came by the CLASS of the network, which you could tell from the first number in the address.

Classless Inter-Domain Routing (CIDR, pronounced "cider") was introduced in 1993 and is the latest refinement to the way IP addresses are interpreted. It replaced the previous generation of IP address syntax, classful networks. Specifically, rather than allocating address blocks on eight-bit (i.e., octet) boundaries forcing 8, 16, or 24-bit prefixes, it used the technique of variable-length subnet masking (VLSM) to allow allocation on arbitrary-length prefixes. CIDR encompasses:



* The VLSM technique of specifying arbitrary length prefix boundaries. A CIDR-compliant address is written with a suffix indicating the number of bits in the prefix length, such as 192.168.0.0/16. This permits more efficient use of increasingly scarce IPv4 addresses.

* The aggregation of multiple contiguous prefixes into supernets, and, wherever possible in the Internet, advertising aggregates, thus reducing the number of entries in the global routing table. Aggregation hides multiple levels of subnetting from the Internet routing table, and reverses the process of "subnetting a subnet" with VLSM.

* The administrative process of allocating address blocks to organizations based on their actual and short-term projected need, rather than the very large or very small blocks required by classful addressing schemes.



IPv6 utilizes the CIDR convention of indicating prefix length with a suffix, but the longer address field of IPv6 made it unnecessary to practice great economy in allocating the minimum amount of address space an organization could justify. The concept of class was never used in IPv6.

Answer 3

classless route is a domain network like in a office or colleges.... the other is the internet network
