<div dir="ltr">My experience is many people use Mozilla's public suffix list for allowing folks to create resources on their app services. This is because a large number of TLDs don't support creating records directly off of them, and the 3rd parties don't want to accidentally grant ownership to a higher namespace to an individual. For example, .uk is a TLD, but you shouldn't let people regirester apps under that because someone could cleverly take <a href="http://co.uk">co.uk</a> and create sub apps within that that they didn't own.<div>

</div>There are google people on this list who (if they haven't already contacted you about it) will no doubt be happy to help you out with that specific problem, in their normal efficient way.<br>

More generally, there are many people who make assumptions about what a valid domain name is. A common example (I find) can be found in web forms which validate e-mail addresses. I can't even remember the number of times I was told that <a href="mailto:jabley@ca.afilias.info">jabley@ca.afilias.info</a> was invalid when I was working for Afilias, which always struck me as pleasantly ironic, especially when the web forms in question were provided by people trying to sell us stuff.<br>
<br>
There's no central registry for broken human expectations of how the DNS works. You pretty much need to just get used to complaining to the people who provide individual broken services when you find them.<br>
