Poor Anguilla - http://ai./ http://ai./
- walid 13y agoWTF! So "ai" is a sub domain of nothing!?
- chewxy 13y agoDNS root domains have no names. That makes http://ai/ http://ai/ a fully qualified domain name. But apparently ICANN has now banned such things. Gods know why. My eyes glazed over after the 10th "whereas". That document reads like a legal document. Ugh
- nknighthb 13y ago> That document reads like a legal document. That's because it is.
- randomdata 13y agohttp://news.ycombinator.com./ http://news.ycombinator.com./
- desas 13y agoA trailing period just represents the top of the domain hierarchy. http://reddit.com./ http://reddit.com./ will work just fine.
- Dylan16807 13y agonews.ycombinator.com is actually news.ycombinator.com. with a period at the end. http://ai./ http://ai./ is basically the same as http://com./ http://com./, except that com doesn't have any IPs configured.
- MichaelGG 13y agoBut as far as TLS name matching goes, it's different. Can something with the dot at the end have a different IP?
- marcosdumay 13y agoNope. If you don't have a "com" domain at your local network, "example.com" and "example.com." point to the same machine. The TLS domain is matched by the web server, it has no relation to DNS, except that both use the same domains.
- nivla 13y ago> Can something with the dot at the end have a different IP? I guess or maybe you can do a hostname match. However, I remember back in the days Microsoft used to use http://microsoft.com http://microsoft.com. as their test site. Now it just yields an error.
- jasomill 13y agoThat's because Microsoft uses hostname-based virtual hosting in IIS, and IIS happens to not recognize HTTP Host headers with trailing dots. This has nothing to do with IP addressing or DNS. In the absence of a resolver search list — which conventionally only applies to names without trailing dot — "microsoft.com" and "microsoft.com." result in the same DNS query, and therefore the same set of IP addresses. Whether this behavior is an obscure bug, a security feature, or both, is left as an exercise.
- kintamanimatt 13y agoFQDNs have periods at the end. It's just convention that dictates they're not included.
- RyJones 13y agoVatican City (http://www.va/ http://www.va/) used to have MX records pointing at va directly (so, pope@va or whatever)
- mrb 13y agoUkraine (.ua) has an MX record on the TLD. So user@ua is a valid address.
- lostlogin 13y agoIf that's his email it must be irritating getting all the old popes mail. Edit: Delivery to the following recipient failed permanently: pope@va
- rdl 13y agoSo did .ai., at least for certain people (or maybe it was just the A record, but A records are enough for mail deliverability in the absence of an MX). I had one, back when I lived next to the .ai. registrar on Anguilla and shared his (very expensive) T1 via 10base2 ethernet.
- guan 13y agoAs far as I can tell they still do: va. 3600 IN MX 100 raphaelmx3.posta.va. va. 3600 IN MX 10 raphaelmx1.posta.va. va. 3600 IN MX 10 raphaelmx2.posta.va.
