The same was said about IP (IPv4). The original solution was a static hostname<>IP address table, "hosts.txt", centrally administered, that all hosts copied via FTP until that became too large. That led to the development of the Domain Name System (DNS) in 1983 [0]. DNS AAAA records do for IPv6 what A records do for IPv4. PTR records (for reverse look-ups) work for both. For zero configuration (no DNS server) we have multicast DNS (mDNS) [1].
