> There was an article on RIPE Labs today about "DomainMON", which is a

> I decided to try this for Yeti.
> * On the first page, where it asked for the domain, I put ".".
> * I was presented with a list of all of the IANA root servers, by name
> and IP address. I unchecked the column "Include this server?" for all
> of them (the were on by default).
> * I then used "Add manually defined servers" and cut & paste the
> results of my local "dig -t ns ." (I have my local resolver using the
> Yeti servers.)
> I did get a bug of some kind. When I added the 2nd server it also
> added d.root-servers.net but with a strange IPv4 address. Clicking
> "X" to remove this from the list of manual entries seemed to work
> fine. This happened again on the 5th server. (My guess is that this
> has something to do with IPv6-only servers.)
> * Adding servers manually re-checks all of the "Include this server?"
> boxes, so I unchecked those again.
> * Going to the next page, the options are:
> * Number of probes (defaults to 10)
> * UDP with frequency (defaults to on, 3600 seconds)
> * TCP with frequency (defaults to off, 3600 seconds)
> * ICMP with frequency (defaults to off, 3600 seconds)
> These defaults cost 167% of my daily credit income. I played with the
> values and opted for:
> * 2 probes
> * UDP on at 3600 seconds
> * TCP on at 7200 seconds
> * ICMP on at 14400 seconds
> With these values it runs at 92% of my daily credit income.
> * I clicked on the green "Monitor" button and got an error page.
> Luckily the actual monitoring seems to have been registered. I can't
> edit the page, but it seems like it is there. When I look at the "my
> measurements" page I see the measurements - and that pesky
> h.root-servers.net. :P
> I've mailed the RIPE NCC to see if they can fix the various issues.
> We may also want more tweaking, because it seems like the probes picked
> may not be those with "good IPv6 connectivity" which basically makes it
> worthless for us.
> Overall it seems like a great tool for watching Yeti though! Or maybe
> that it *will be*. I remain hopeful, and will let you know how it
