Kevin,
I found the issue. It is on Level3. Level3 gave away two /48 IPv6 subnet to=
his client, but when in their network, they summaries the subnet to /32. I=
do not believe they advertised out to the whole world an existing /48. I w=
orked with another upstream provider whom their upstream is Level3, and the=
y said they only see one /32. So, whoever use Level3 as their upstream prov=
ider will have issue accessing to these IPv6 subnet. I already worked with =
Level3 yesterday evening on this.

Kevin,
May I know where do you get this ipv6 address? I checked ARIN, and it belon=
gs to Level3. But it does not seems to me when I try to traceroute to this =
address.
Thanks.
Keng Soon

Hi,
My name is Keng Soon Goh, and I work for Hughes Network Systems. One of my =
client try to access to you websites, and at some point, it does not go any=
where. I talked to Level3, and they said this subnet is belongs to them, bu=
t there is no routes at all. Are you planning to advertise this IPv6 addres=
s to the internet?
Thanks.

Talk to your provider. I have no problem reaching it, so looks like your pr=
ovider lacks a full IPv6 table.

I'm now confused. The address is the one in your message. It was in tte res=
ponse to the nslookup you copied into your message The address is from a L=
3 block, but is being announced by Yahoo!. We peer directly with Yahoo! in =
San Jose (and other places). I see no indication that Level(3) is involved =
in any way other than owning hte net block that Yahoo uses.
I don't have IPv6 at home, but the HE looking glass also routes to an Equin=
ix exchange and directly to yahoo and on to www.freebsd.org<http://www.free=
bsd.org>. If I try to trace from a Level(3) looking glass, it fails. someth=
ing very odd id going on. Looks like Level(3) forgot that the address was a=
ssigned to FreeBSD and is not accepting the Yahoo! route or something simil=
ar.
