Greetings again. Based on some great input from Evan Hunt, we have updated our draft. The algorithm is both simpler and easier to configure. In fact, we have examples of how to configure BIND and Unbound/NSD to match the new spec. We'll be talking about the new draft in today's meeting. --Paul

This sounded good until Note that using this configuration will cause the recursive resolver to fail if the local root zone server fails. Could I use forward first instead of static-stub so that it would fall back to the normal root servers if the local root server could not get zone transfers or

[DNSOP] Spartacus and new record types

2014-11-11 Thread Stephane Bortzmeyer
Does anyone know how Spartacus (draft-dickson-dnsop-spartacus-{lang,system}, on the agenda for today) handles new record types that may be invented tomorrow? I find nothing in the drafts, which describe the JSON structure for today's record types, but not for future types.

I'll take a dollar for every query in PTR we take at the ipv4 /8 and Ipv6 /12 level. Thats somewhere around 170,000/sec. Luckily, you'll all stop before I have the entire western economy in my pocket, but thats ok. I'll take the cents.. I'll take the millicents... Seriously: the volume of query

[DNSOP] Using PTRs for security validation is stupid

2014-11-11 Thread Lee Howard
Many SSH servers (by default) reject connections from IP addresses without PTRs. This is stupid. I heard applause during the WG meeting in response to these statements; sounded like consensus to me. I said I would check that consensus on list. Thanks, Lee
