The Mismanagement of IP Addresses: How the Inventors of the Internet Failed

👀The inventors of the internet did not anticipate the demand for IP addresses and mismanaged the allocation process.

💡Class A, B, and C addresses were used, with Class A having a large number of addresses per network and Class C having a smaller number.

🔄Loopback addresses, starting with 127, are used for network testing and cannot be assigned to devices.

✨Class D addresses are reserved for multicast, while Class E addresses are experimental and not used currently.

🛠️Subnet masks determine the number of networks and hosts available in each class.

Why did the inventors of the internet mismanage IP address allocation?

—The inventors of the internet did not anticipate the growth and demand for IP addresses, leading to mismanagement and allocation of addresses.

What are loopback addresses used for?

—Loopback addresses are used for network testing and are assigned to the local computer to check if the network is functioning properly.

Are Class D and E addresses commonly used?

—No, Class D addresses are used for multicast, while Class E addresses are experimental and not currently used.

How do subnet masks affect the number of networks and hosts in each class?

—Subnet masks determine the number of networks and hosts available in each class. Class A has a larger number of addresses per network, while Class C has a smaller number.

What is the purpose of IP address allocation?

—IP address allocation ensures that each device on the internet has a unique address to communicate with other devices.
