IPv4 is "good enough", but we could do some things to extend its usage further.
First, adopt service location in DNS, and being to retire it at the TCP port-number layer. Then we could run more than one website per ip address, and this would significantly increase resilience against censorship. Rotating ports for censored websites is a significantly easier task than rotating IPs for them since it does not involve routing changes. This could be done with "here and now" technology.

- exabrial 2y agoWasn't aware of this actually, whats the issue with them?
- cyberax 2y agoIf you're using solely the flow labels to do load balancing, malicious clients can force traffic to come through only one load balancer by setting the same flow label. You need to add the source IP/port into the mix. But they alone are in practice enough for decent load balancing.
