AARNet AS7575 announcing, and soon

As part of the ongoing measurement of traffic in three /24s from the range are shortly going to be announced by AARNet, via AS7575:

This will be happening over the next week or so.



Hey George,

If AARNet or someone has the bandwidth, would it not be of value to announce the entire 1/8 and see what areas are targeted by traffic - clearly analysing it and removing DoS or scan traffic.

I'm just wondering if there are any /24's or space that is unsuitable to allocate inside 1/8.


If only there was someone who pushed a whole lot of outbound data and had not really that much inbound - advertising 1/8 wouldn't really impact them that much. Some kind of, video sharing site, maybe?

"Accordingly, APNIC authorizes AS36351 to periodically advertise a
route for from now until 21 March 2010, and
requests that AS36351's peers and upstreams accept this as a
legitimate routing advertisement."

:slight_smile: has been fun. I wont steal George/Geoff's show by telling
all... but I will state that about 18% of the internet is still bogon
filtering (or using internally) 1.x... I wouldn't want to be a poor
schlub getting assigned something from this space, personally.

We're going to announce in the next 24 hours as well...
To see what backscatter is like in an uninteresting range. I'll send
a separate clear message to the list about this too. :slight_smile:
