An IP address is the numeric label that identifies a device on a network — 93.184.216.34 in the older IPv4 format, or a longer hexadecimal string like 2606:2800:220:1:248:1893:25c8:1946 in IPv6, which exists because the world ran out of IPv4 space. The whole point of the DNS is to map a human-friendly domain to one of these addresses: an A record points a name at an IPv4 address, an AAAA record at IPv6. Blocks of addresses are allocated through IANA to regional registries. Domain tokenization operates a layer above all this — it changes who owns the name, not the addresses the name resolves to.
