Final answer:
A single hostname can indeed correspond to a single IP address via DNS, which is the internet's system for translating human-readable hostnames into machine-identifiable IP addresses.
Step-by-step explanation:
The statement that a single hostname may correspond to a single IP address is true. This is a fundamental concept in networking known as DNS (Domain Name System). DNS acts as the phonebook of the internet, translating human-readable hostnames like 'www.example.com' into IP addresses like 93.184.216.34 that computers use to identify each other on the network. However, it is also true that a single hostname can point to multiple IP addresses for purposes such as load balancing or redundancy, and conversely, a single IP address can serve multiple hostnames, which is common in shared hosting scenarios.
