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.

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.

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.

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.
