ayi Is there a maximum allowed subdomain depth supported by webservers ou browsers? Par exemple, could a domain like foo.bar.baz.monkey.pirate.google.com cause problems?
ayi Je crois le DNS itself can have up to 127 levels of label, chaque label can be up to 63 characters et le maximum length of le whole record is limited to 253 characters as you have to encode le length et a terminating 0.
