| Question 764 |
In Ipv4 addresses, classful addressing is replaced with:
| Classless addressing | |
| Classful addressing | |
| Subnet advertising | |
| None of the options |
Question 764 Explanation:
→ Classful addressing is replaced with classless addressing.
→ The problem with this classful addressing method is that millions of class A address are wasted, many of the class B address are wasted, whereas, number of addresses available in class C is so small that it cannot cater the needs of organizations.
→ Class D addresses are used for multicast routing, and are therefore available as a single block only. Class E addresses are reserved.
Note: Because of these problems, Classful networking was replaced by Classless Inter-Domain Routing (CIDR) in 1993.
