Newbie question: Would it work for publishers to key off of IP address instead of using cookies?
- hedora 7y agoYes, but with a significant false positive rate due to IP address sharing, and you can get more articles by switching IP’s (unless someone else exhausted the new IP before you got it).
- eof 7y agoNot really. Problems arise when you have many people behind the same IP. You can hand-wave this problem away for family units behind a router, but you'll soon find out there are entire institutions (schools, office buildings with lots of unrelated companies in them, etc) that will share an IP.

- paxswill 7y agoLarge scale NAT is one reason that would fail. Some mobile carriers have most of their customers behind a handful of IPs. Wikipedia has dealt with this a lot, and has a page explaining why conflating an IP address to a person isn't usually the way to go. https://en.wikipedia.org/wiki/Wikipedia:IP_addresses_are_not_people https://en.wikipedia.org/wiki/Wikipedia:IP_addresses_are_not...
- ronsor 7y agoit works for IPv6 (where one IPv6 address really does equal one person)
