- In classless addressing, can two different blocks have the same prefix length? Explain.How is an Internet Protocol (IP) address different from a domain name? What are the benefits of mnemonic addresses? Exists a limit to the number of domains a 32-bit representation can store? Exists a maximum number of computers that a domain may contain?For NAT Network Address Translation Scenario: Jenny Bello is a small business owner selling and making customized computer peripherals. She has been finding it difficult to track her sales and inventories, however recently after an expert's advice, she adopted a Point of Sale (PoS) server. So, she can now track her sales and inventories at the store. However, she ran into another issue, the server can only be accessed within the store, because it has been assigned a private IPv4 address, it is not publicly accessible via the Internet. a) Why is not having the PoS server accessible over the Internet a problem for the business? b) What caused this problem? c) Propose a solution for the problem and explain how the solution works.
