We've thought about letting people turn it on or off, but have held off for now. We're only sending the edns-option to authoritative DNS providers who also handle the HTTP request, and thus would have seen the entire src_ip anyways.
- jcr 15y agoDavid, I hope you'll forgive me for asking questions before I'm done reading the draft, but I'm curious about one thing. Are there any known effects on client-side caching? I can't think of any, but the rise in high latency links on the last hop (particularly mobile, but to a lesser degree WiMax, satellite, ...) is one of the places where client-side caching (including dns caching) can make a big difference. If you've ever seen the painfully common DNS issues on Verizon Wireless, you'd know why I'm asking. ;)
- stock_toaster 15y ago> We're only sending the edns-option to authoritative nameservers who also handle the HTTP request Authoritative nameservers handling http requests? Mine certainly don't. Or did you mean to say that you only send edns-option to the server that is authoritative for the domain being requested?
- davidu 15y agoclarified language.
