Because the second level domain is far more important than the subdomain. The second level. www.example.com and example.com usually have the same contents, but are always controlled by the same group.
- meowface 8y agoExactly; wish I had added that to my original point.
- hunter2_ 8y agoIt's not true that the second level and third level are always controlled by the same group (most of .uk for example). You can put an SOA record anywhere.

- markovbot 8y agoAre they not respecting the public suffix list?
- jlarocco 8y agoBut the entity that controls the second level domain always controls all of its subdomains, not just www. Historically www has been a special case, but that's not a requirement and that's on the decline. It seems like the confusion this change causes negates any benefit it could have.
