Fewer bad examples for mail Email

The DNS has always had a few names for use as examples in documentation, domains example.com, example.org, example.org, and example.edu. In 1999 RFC 2606 formally reserved the first three.

There's nothing technically special about these names, which have normal WHOIS and DNS entries, managed by IANA. Until recently, that meant that even though none of them handle any e-mail, mail sent to them by mistake worked badly.

What does blockchain have to do with voting? Internet

Apropos of recent news stories about a blockchain based voting system that was hacked before its first election, someone asked:

Perhaps final recognition that a lot of blockchain is hype? Or simply an interesting side-story?

A blockchain can ensure that the lies you see are the same lies that were published, but that doesn't have much to do with voting.

Voting has a very peculiar security model -- you need to verify that each person voted at most once, you need to count all of the votes for each candidate, and you need not to link the two. A lot of very bad voting systems are built by people who wrongly assume that its security model is similar to something else, which it is not.

An obvious example is Diebold who built voting machines that worked like ATMs, which was a disaster, since the way you audit ATMs depends on the details of each transaction being linked to the person doing it.

Paper ballots have a lot to recommend them. It's easy for poll workers to observe that each voter puts one ballot into the box, they're relatively easy to count (we use mark sense machines here) and compared to the spaghetti code in direct recording machines, they're quite tamper resistant.

What does it mean to Deploy DMARC? Email
The IETF's
DMARC working group is thinking about a maintenance update to the DMARC spec, fixing bits that are unclear and perhaps changing it where what mail servers do doesn't exactly agree with what it says. Someone noted that a lot of mailers claim to have ``deployed DMARC'', and it's not at at all clear what that really means.

Dead TLDs break 50 ICANN
Last November I wrote
a post observing that with .DOHA and .ZIPPO handing back the keys to their TLDS, the count of abandonded TLDs had reached 45, and I wondered how much other destroyed value was hiding in new TLDs.

Domain Name Variants Still Won't Work ICANN

ICANN has spent years trying to figure out what to do with domain name variants, strings that look different but mean the same thing, for some definition of "the same." They've been trying to deal with them in second level domains for a decade, and are now working on rules to allow variant top-level domains.

Unfortunately, variants don't work. The problem isn't putting them in the DNS, it's that once they're in the DNS, they don't work anywhere else.

A short history of DNS over HTTP (so far) Internet
The IETF is in the midst of a vigorous debate about DNS over HTTP or DNS over HTTPS, abbreviated as DoH. How did we get there, and where do we go from here?

What's wrong with this security model? Internet
I'm moving some of my financial accounts to Lively, a fintech startup. We've had the usual chit-chat about details of where the money is coming from on the messaging system on their web site. It works fine, when there's something new they send me a note saying to log in and check my messages. Except that today they sent me a message through a third party "secure" messaging service. To protect the guilty, we'll call it Hubri.
