Used up the gandi.net coupon codes

Since nobody wanted my coupon codes, I ended up getting the following for a whopping 1.17€ (incuding VAT)

  • dynamic-ip.xyz
  • home-ip.xyz
  • home-server.xyz
  • luxtrust.me
  • whiskeytangofoxtrot.eu

The first three are obviously for my Dynamic DNS service.  Want a subdomain one one of these (or ipv4.lu)?  Give me a sign.

The whiskeytangofoxtrot.eu one was just because I tried so many .eu and nothing interesting was free, so I typed that and it was available.  No idea what I’m going to do with that.  Dynamic DNS service is also ok, I think.

Now, luxtrust.me came on a whim.  These .me domains work best with a verb, like “help”, “instruct”, etc… Obviously, “trust.me” came up in my mind and even more obviously, it was taken.  But, luxtrust.me was free.  Too good to let it slide.
I might setup email forwarding for it, so I can give LuxTrust an email like “angrycustomer@luxtrust.me”.  I’ve got 1000 free forwards, so I might even give them away to anyone who wants. *grin*

The attentive reader will notice that the .com at 50% off is not listed.  That’s the only one I managed to give away.

Free .xyz domain

As I mentioned in my .lu 3-letter domain analysis, I got a few codes at Gandi to get certain TLDs for free or at discount for one year. In all fairness, I have not much use for them and the cool ones seem to be long gone. After the free first year, I’ll have to pay for them any way. I have 9 domain names (ignoring those where I’m marked “technical contact” only and ignoring willekens.lu, owned by my father), which totals to 202.50€ per year. For a private person and just for a hobby, that’s do-able, but not exactly cheap. Okay, hobbies cost money. C’est la vie.

I also, offer Dynamic DNS services to friends and family. I have two domains dedicated to this, namely ipv4.lu and homesupport.lu. The former is for nerdy friends over the world, who want their home connection to be accessible. The latter, I mainly use for family so I can support them using RDP over SSH or VLC over SSH. You can’t ask me to get one under that domain, I decide that for you.

Basically, you could have something like marvin.ipv4.lu pointing to your home connection, and all through the magic of some scripts and two VPSes I rent (one in the US, one in the EU, for redundancy). I can, however, understand that the ipv4.lu doesn’t appeal to many non-Luxembourgish nerds.

So, if there would be any interest, I could get a few extra domains for the Dynamic DNS service. The codes at Gandi, I have are:

  • 3× .xyz for free
  • 1× .me for free
  • 1× .eu for 1€
  • 1× 50% off for a .com

I checked, stuff like “home-ip.xyz”, “home-connection.xzy” and “home-server.xyz” are still available. Personally, I have trouble finding anything with .me that makes sense and is available and the rest are for-pay. Now, of course, if you have a great idea for either of the ones listed above, you can tell me.

Now, if you think my Dynamic DNS service is good as-is and really, really, really need that the coupon for your own usage, just ask nicely. I might even be in a good mood and just give it to you. The coupons expire the 1st May 2015.

Three letter ccTLD domains

My registrar of choice, Gandi, had its 15th anniversary this month. Apparently, I’ve been a customer for 15 years too. Has it been that long? Anyway, they gave away prizes and I’ve got codes for three free .xyz, one free .me, a .com at 50% and a .eu at 1€. To be entirely frank, I have no idea what to do with any of those codes1, but as you do when you get something for free, you tend to look what’s up for grabs. As the shortest, non-grandfathered, domain names you seem to be able to get are three letters long, I tried a few for .xyz and to my surprise I saw that the corresponding .lu was free.

That was a surprise. I’d have expected that most, if not all, three letter .lu domains would be taken. So I decided to investigate. A quick one-liner pounded the whois servers, and, well, I got banned quite quickly at my work IP address. I should have foreseen that. You might have seen a Facebook status about it, and someone suggested to first look whether there are DNS records2 and, then, and only then do the whois checks3. I decided to do exactly that and I ended up with 14291 three letter domains that have no valid DNS entries. That’s an amazingly a small amount. There are 26×26×26 = 17576 possibilites4, which means only 19% of all three letter .lu domain names have DNS entries.

Now, what? That’s way too much for bulk querying the whois servers and I had no desire to get my home IP blacklisted. My plan was to do one whois every 20 minutes, but that would make nearly 200 days. I decided to go manually over the list and pick the ones that caught my eye. I’m human, I get bored, so that’s probably why I selected more at the beginning of the alphabet. Anyway, I selected 87 domains for investigation and it turned out that 71 of those were not registered. Some examples (but really, just a few):

  • ado.lu : “ado” is French for teenager.
  • aes.lu : Advanced Encryption Standard. Neat to have as nerd.
  • asm.lu : Nobody in the demo scene got this? Seriously?
  • foo.lu, bar.lu, and baz.lu : Yes, you can still have the full metasyntactic-variable sequence. That “bar.lu” is isn’t taken, is simply amazing.
  • bbw.lu : I am so tempted to get this one.
  • bid.lu : For an auction site?
  • fac.lu : In French “la fac” is pretty much the colloquial equivalent of university.
  • fkk.lu : The Germans will understand.
  • gnu.lu : All hail Richard Stallmann!
  • jiz.lu : If you don’t know why, you need to have your perversion levels adjusted.
  • jts.lu : Ok, this one only means something to me. Online I get referred to as JTS. I don’t know when people started to do that, but I guess it’s because “jawtheshark” is too long.
  • nan.lu : Not a number. Another nerdy one.
  • pdp.lu : Neeeeerd! You should also take vms.lu, which is also available.
  • pie.lu : The cake is a lie, but the pie isn’t.
  • ocr.lu : Optical character recognition. I could see value in this if you’re in document management.
  • raw.lu : Calling the photography nerds… or for weird porn.
  • tit.lu : Again, I’m so tempted to take this one.
  • xen.lu : I should get this one, just for when I need to go freelance and want to offer virtualization services.
  • zzz.lu : Because I really got sleepy after going through so many domain names.

You can get the full list of the ones I verified as “not registerd”. (List without DNS entries) A .lu is free to register for everyone, worldwide and costs about 25€ per year.


Addenum
Apparently, while creating this post, I opened up the wrong list, namely the DNS verified one. My mistake. A few listed here are not free and haven’t been for a while. Those are foo.lu and bar.lu. No metasyntactic-variables for you. Sorry.


1I could add a few to my “free-for-friends” dynamic DNS. For now you can only get a subdomain of ipv4.lu.
2 Script used: for domain in `echo {a..z}{a..z}{a..z}`; do if [[ -n `host $domain.lu | grep NXDOMAIN` ]]; then echo $domain.lu; fi; done > threeletters.txt
3 Script used: for domain in `cat selected-domains.txt` ; do QUERY=`whois ${domain} | grep "% No such domain"` ; if [[ -n "${QUERY}" ]]; then echo ${domain} is free ; fi ; sleep 1200 ; done > available-threeletter.txt
4 Ignoring numbers, which would expand the search space a bit more.
