==== Network Basics ====

The IETF 76 network connects to the Internet via a GE
circuit through Japanese R&E NWs, IXs and Japanese major
ISPs.  The meeting and overflow hotels are covered by and 2001:dfb::/32.

The IPv4 network address is provided by DHCP, while IPv6
address is provided via DHVP6-lite and Dynamic
Auto-configuration for IPv6.

==== Wireless ====

An 802.11 a/b/g wireless network is being provided
liberally in the ANA Crowne Plaza Hotel Hiroshima. The
areas being specifically covered are the meeting rooms and
hallways in the conference area, the main lobby, 7th floor
meeting rooms and 22nd floor meeting rooms.

To use this network, associate with the beaconed SSID of
"ietf" for 802.11b/g and 802.11a/n and "ietf-a" for
802.11a/n.  WPA2-AES-PSK is also provided both 802.11b/g
and 802.11a/n "ietf.wpa" and 802.11a/n "ietf-a.wpa" with
"hiroshimaJAPAN" as the wpa-passphrase.

The proper operation of the wireless network requires the
assistance of all users.  One of the most significant
issues with wireless performance in past IETF meetings has
been wireless clients automatically, or accidentally
initiating "ad-hoc" networks that act as the official IETF
wireless network, causing other users to associate with
false IETF wireless networks.  Therefore, please disable
your client's ability to create an ad-hoc network and as
well as the ability to automatically join an ad-hoc
network.  If you are using Windows XP or Mac OS X 10.4 and
10.5 to manage your wireless client, the instructions to
disable creation of ad-hoc networks are listed below. If
you are using other systems, please do whatever your
particular wireless client management system requires to
turn off ad-hoc networks.

  == Instructions for Mac OS X ==
  Open System Preferences -> Network -> Airport -> Options
and un-check the box for "Create Computer-to-Computer
networks". == Instructions for Windows XP
  Open Properties -> wireless networks -> advanced and then
select "access point (infrastructure) networks only" and
unselect "automatically connect to non-preferred networks".

==== Guest Rooms in the Venue and Overflow Hotels ====

The IETF 76 network is also provided in your Internet room
access at all IETF hotels (ANA, Sun Route, Mitsui Garden,
Oriental, Rihga Royal, and Granvia), both IPv4 and IPv6
identical to the conference area. The hotel network will be
rolled back to original configurations between 11am and 2pm
on November 13th, Friday.

==== Terminal Rooms ====

There are two terminal rooms - Matsu room and Wedding Hall
both on the 4th floor of the ANA Crowne Plaza Hotel
Hiroshima. There are approximately 24 seats in Matsu room
and 36 seats in Wedding Hall with wired 10/100/1000
Ethernet access and 100V/60Hz Japanese (power outlet is as
same as North American type) power outlets. No food or
drink in the terminal rooms, please!

While Matsu room is open 24 hours a day until 5pm on Friday
November 13th, Wedding Hall is open only from 8am to 8pm
and available until noon on Friday November 13th. In Matsu
room there is a monochrome and a color laser printer.  They
are IPv6 ready.

A help desk is being provided from 8am to 8pm every day in
Wedding Hall.

==== NOC ====

If you need to report a problem to the NOC, either stop by
the help desk located in Wedding Hall terminal room, or
send an email to noc@meeting.ietf.org and the Jabber room
at noc@jabber.ietf.org.

==== Printing ====

Two IPv6 enabled printers are located in the Terminal Rooms
(one for each room). The printers themselves are RICOH
Aficio SP 4210 (monochrome; printer1.meeting.ietf.org: in
Wedding Hall) and RICOH Aficio SP C820 (color:
printer2.meeting.ietf.org: in Matsu room). C820 is
Postscript capable and have the duplex option installed.
The printers are accessible via LPD and IPP.  The paper
size is A4 only, and any letter size printing may result in
A4 output. Detailed printing instructions will be available
in each terminal room.

==== Services ====

The following network services are provided:
  == SMTP
	smtp.meeting.ietf.org (IPv4:, IPv6:
	2001:dfb:0:8::25) SMTP relay services are provided
for users on the IETF network.
  == NTP
	ntp.meeting.ietf.org (IPv4:, IPv6:
	2001:dfb:0:8::123) Stratum 2 time service is
provided via IPv4 and IPv6 unicast.

Additionally, recursive DNS service is provided by two
servers (ns2.meeting.ietf.org,,
2001:dfb:0:8::53), and (ns.meeting.ietf.org,,
2001:dfb:0:9:53). They don't accept any dynamic DNS update

Our domain name is meeting.ietf.org.

==== Thanks ====

The terminal room and IETF network are made possible by the
generous contributions by a number of companies and by the
tireless efforts of our volunteer team. If you see any of
these people in the halls, please be sure to thank them for
all their work!
