Hosting with DynDNS

Complicated. I.e., when using DynDNS, you effectivly can't host anything on your root domain, because:

• You need to use CNAME records to point to the dynamic DNS entry
• You want a SPF TXT root record but you can't have both TXT and CNAME records for the same (sub)domain as of RFC1034, section 3.6.2

So you need to serve services in subdomain, i.e. www, or matrix (see ~/Howtos/im/matrix/federation.md
