Question

what is necessary to plan and use when implementing a network?
ip addressing scheme
printer location
mac addressing scheme
device names

Explanation:

When implementing a network, an IP (Internet Protocol) addressing scheme is crucial. IP addresses are used to identify devices on a network and enable communication between them. A printer location is more relevant to office layout or device placement within a local area rather than core network implementation. MAC (Media Access Control) addresses are unique to network interfaces but are typically managed at a lower - level (by the hardware and data link layer) and not something that is "planned" in the same way as an IP addressing scheme for network implementation. Device names are more for user - friendly identification and not a fundamental requirement for the technical implementation of a network's communication infrastructure.
