Just a small issue; you mention that in the updated validator you’ll accept “”@example.com and benedictXIII@va and simply output a warning — except you don’t seem to have done this for the former (tests #31 and #153).

Comment on What does a double colon mean in IPv6 addresses? by Kaeso

Oh, wow! Then it’s bigger than I thought :)
I think the only way to sort this is to directly ask IETF for clarification (6man WG, maybe)…

I've checked this in .NET, and while the IPAddress parser will accept double-colon for a single zero-group, it will never emit one. Perfect!

Hi Luca,

It was Michael Rushton who alerted me to the issue in an email. He then raised the erratum you mention, and another one (to the opposite effect) in RFC 4291. The intention was to wait to see which was verified and use that as the deciding ruling.

Unfortunately hardly anybody reads the errata because they are never incorporated into the main body of the RFC. Thus plenty of people still believe the travesty that is RFC 3696. The original confusion will remain until either RFC 5321 and RFC 4291 is obsoleted.

RFC 5952 is a recommendation for good practice rather than a definition of correctness. Thus all the unpleasantness from RFC 4291 is still “correct” despite being deprecated by RFC 5952.

I love the IETF.

Hi Sameer,

Check the comments here: http://www.dominicsayers.com/isemail/

You’ll see a couple of people have mentioned Java versions of my code. Nobody has submitted any code to me for inclusion but you could try getting in touch with the commenters.

Have anyone tried to write or convert (Somehow) Dominic’s validation code into Java. I am gonna attempt to do that but wanted to know if anyone has done it, as they say “A good programmer is a lazy programmer” :D

The mess is actually bigger than that. RFC 5952 specifically updates RFC 4291, so one should really behave accordingly to its section 4.2.2 as you quoted. Unfortunately, RFC 5321 is currently undergoing a fix with Errata-ID: 2467, as to being able to short a single 16-bit group of zeroes. If somebody actually care about this mess, IMHO that errata should be rejected.

Hi Dominic

Comment on Trying to recover my compromised Hotmail account by Lucy

I too have been trying to close my hacked hotmail account that I can’t get in anymore. So if your can give me direct link for the form I will fill it like you did and wait.

Hope they get their act together and close these hackers in côte d’Ivoire…
