the.com/domain name

means The human-readable address (like example.com) that stands in for a website's actual numeric location on the internet.

from From 'domain,' a territory under one ruler's control, tracing back to Latin 'dominium' (ownership, lordship) and 'dominus' (master, lord). When the Domain Name System was built in the early 1980s to replace clunky numeric internet addresses with memorable names, the word was already perfect: each name marks out a little ruled territory on the network, with someone — or some registrar invoice — as its lord.
