There's no Place Like ::1

So lately, I am having problems accessing my 0x82.com at home. This domain sits on a dynamic IP address, and I use editdns to update the DNS records.

EditDNS advertises my A record with a 0 TTL. However, I found that my ISP Sapo caches the record with a huge TTL:

0x82.com.        604800    IN    A    82.155.174.2

Before I shout “what th f0ck are wrong with this guys”, I still have to do a quick read of the relevant RFC, because I think that a 0 TTL may not be a “standard” thing…

As always, if you know something about this, please shoot! :-)
