IPv6 is a one-page solution too, if you ignore all of the actual details.
As a small example, consider these two paragraphs that the page says for DNS:
Name to address mapping is performed with the AX record. AX returns a 64-bit IP address instead of a 32-bit IP address. A DNS server which supports IPxl should automatically translate any known A records for a given name to AX records by prepending 0.0.0.1 to the address. It should likewise automatically translate any AX records with the prefix 0.0.0.1 into A records.
PTR records for IPxl are located under "ipxl.arpa" and work the same way as the records in "in-addr.arpa". A special tree will be created for *.184.108.40.206.ipxl.arpa which CNAMEs each individual record to the respective record in in-addr.arpa leaving the in-addr.arpa zone authoritative.
And here's what the v6 equivalent would look like:
Name to address mapping is performed with the AAAA record. AAAA returns a 128-bit IP address instead of a 32-bit IP address.
PTR records for IPv6 are located under "ip6.arpa" and work in much the same way as the records in "in-addr.arpa", except that each level of the hierarchy represents one hex nibble rather than one byte.
It's a lot simpler, even. And then it comes time to actually specify the standards, and you need to issue an RFC that adds an AAAA (AX) record type to DNS, and an RFC that specifies rDNS and instructs IANA to create the reverse zone, and RFCs that tell people how to handle a mixture of AAAA (AX) and A, and RFCs that cover SMTP's MX record interaction with AAAAs/AXs, and oh let's not forget that there's no standard API for looking up non-A records in programs so you've got to specify that too.
The only reason IPv6 is so "complicated" is because we did go through and specify the necessary changes to all affected protocols. All of these "one page alternatives" would've had to do the exact same thing to get them operational, and thus would have ended up with just as much "make-work" as v6. Except it's not make work, it's the necessary work to support expanded addresses.
