It exists to facilitate MTU discovery for DTLS (which is basically TLS over UDP). By using heartbeats a sender could send a message to the server and infer through responses and non-responses (and maybe some kind of binary search) what the

There's a common cliché, that C programs, as embodied in Unix, are probably the most widely used form of functional programming - or at least CSP. This example is idiomatic; grep -c foo * | uniq | sort -rn It's more than

Disclaimer: I work on Route 53. You can ALIAS to record sets within your own zone too, which can contain any arbitrary IP. This is useful when composing routing types (e.g. weighted plus latency). But we don't support ALIASing to recor

Thanks! that looks like they are running standalone resolvers: inetnum: 195.174.0.0 - 195.175.255.255 netname: TR-TELEKOM-960902 descr: Turk Telekomunikasyon Anonim Sirketi in that case, each ISP is p

If anyone is in Turkey and can configure their system to use Google Public DNS IPs / OpenDNS IPs as their resolvers, I'd be interested to learn what you see on: http://whatsmyresolver.stdlib.net/ It's clear t

Here in Seattle, new buildings are required to be mixed-use in many areas. But there seems to be a glut of commercial tenants for the locations. About 3 out of 5 of these buildings seem to fill up quickly with residential tenants (and risin

Wow, this is going to be a great read. First impressions: pretty decent comment to code ratio, only about 30k lines of actual code, all of the code uses carriage-return newlines (though who knows if that's an artifact of archival) as d

Another option would be to put a 5mm embossed "K" on the bottom of the container, and call it a trademark, or trade-dress. Then make the receptacle require that exact "K" as a physical lock.

For a long time I looked around at the relative lack of 40+ developers and founders in my field and considered it worrisome; what will I do when I get to that age? do I need a massive bank of savings just in case? But I think it's also

That's one sort of "fairly" - that employees should participate in profit sharing and that their compensation should be tied directly to the value they create (though should employees also share in the losses?). Another kind

End-to-end security isn't the same thing as encryption or privacy. The goal of DNSSEC seems to be to authenticate that DNS answers are correct. In an end-to-end security model, then as you suggest - your browser should be involved, and

I've implemented DNSSEC twice now, I've also implemented IPv6 several times - at various levels of the stack (including directly at layer 3) and have had a hand in two different SSL/TLS implementations. Having implemented eac

The argument about US "control" of ICANN has always seemed a little surreal to me. I took this photo on the roof-top deck at ICANN (they know how to throw a good party!) : http://www.flickr.com/photos/90065267

People often think that the N-queens problem is just an abstract exercise, good sample work that stretches the mind. But when we were building Route 53, we actually use the N-queens problem, it's part of how we assign Shuffle Shards;

In general resolvers look up one type and cache the result for that one type. CNAMEs are special; firstly clients never lookup CNAMEs, it's never the qtype. A CNAME is a special kind of answer that says "This name should be consid

by colmmacc 13y ago
It is confusing, but the difference is that a CNAME is cacheable for queries all types. For example, let's say I query the resolver for qname=example.com qtype=AAAA. The resolver finds the CNAME from example.com to foo.example.org and

The problem doesn't have much to do with particular mail servers, but rather with the order in which queries may be made. Let's say the following two records are allowed to co-exist: example.com 60 IN MX mail.example.com

No, registrar's are your portal to updating data in TLDs, but those TLDs are each operated separately. .com and .net are operated by Verisign, for example.

It's definitely on our list, but in the meantime there is https://code.google.com/p/route53d/ which will let you translate an AXFR/IXFR from a bind server directly into Route 53 authenticated calls.

Hi, I work on Route 53, can you clarify; are you seeing a problem from your registrar when you try to move to Route 53? We're also always keen to hear about features customers would like.

Most resolvers rotate the records in a record set on every query. The main thinking behind this is so that all of the resolver's clients don't just hammer the first IP in a multi-IP recordset. Some resolvers make exceptions to thi
