You can though, there is an options field in IPv4 that could have been made to hold extended address values.
It was used as part of the Extended Internet Protocol: https://www.rfc-editor.org/rfc/rfc1385 https://www.rfc-editor.org/rfc/rfc1385
And the Address Extension protocol aka IPv7: https://www.rfc-editor.org/rfc/rfc1475 https://www.rfc-editor.org/rfc/rfc1475

- CoolGuySteve 4y agoRouters already support the Options field, it's part of IPv4. The old RFCs mentioned are specifically designed so only routers at the edge need to support them. You should try reading the specs before making technical claims instead of completely missing the point of why those RFCs were created in the first place. Instead we have to rehash an argument from 30 years ago.
