The other day I found an undelivered message from one of my users in the mail queue; the MX on the receiving side had rejected it because my MTA's address had no reverse lookup in the DNS. WTF? Ah, it had no reverse lookup for its IPv6 address! So I learned that freenet does indeed accept mail via IPv6. (Only not from me, currently.) That's nice!

I really have to get that straight. rh-tec's web interface for configuring reverse lookup(s?) is, to say the least, not really self-explanatory, and my question about the interface and about delegation from December is still unanswered. I am going to push that again.

My DSL link was switched from 6 Mbps to 16 Mbps downlink yesterday, and from 512 kbps to 1 Mbps uplink. Don't know why they needed 15 minutes downtime for that. At first the downlink speed was much less, around 700-800 KB/s; apparently the modems had negotiated something more agreeable an hour later.

I ordered the upgrade mainly for the uplink; it was always a pain to upload largish photo collections or other bandwidth testing material. Should feel at least a bit better now, although a factor of two is not that much. The faster downlink is sure nice, but not really necessary. I'd rather trade the 16/1 Mbps for, say, 12/5. But this is not an option with the DTAG.

But still, yay!

This is, of course, not related to IPv6 at all.
