Connectivity
The Sheraton is linked to the Internet via a wireless link to the Utah Education Network. Native IPv6
routing, native multicast routing, and Internet2/Abilene connectivity are
provided in cooperation with the University
of Utah.
Mail Relay
If you need a local mail relay, use smtp.nanog28.merit.net.
Terminal Room
UEN and the University of Utah have equipped the NANOG terminal room with
10
workstations, a printer, outlets and ports for laptop users, and
802.11/802.11b wireless connectivity.
The terminal room is in the Summer room near the
Ballroom, and will be open from Sunday afternoon to the end of the
meeting, with 24-hour access. You will need your NANOG badge to enter.
The account on the Unix workstations is:
login: nanog
password: nanog
Main Room
The main ballroom will have tables set up with ethernet ports for laptop
users, as well as wireless connectivity. We're also hoping to get wireless
connectivity to the bar area(s), and to the Beer 'n Gear. Connectivity to
the Beer 'n Gear is not guaranteed.
Wireless Connectivity
Please read our note about avoiding cleartext passwords.
Merit is providing 90 wireless cards for loan to attendees during the
meeting. Cards will be available in registration area on Sunday
afternoon, and in the main ballroom on Monday and Tuesday.
SSID
The wireless network SSID is nanog28 .
Supported Cards
The network supports 802.11/802.11b-compliant, Direct Sequence, spread 2.4
GHz (DS) cards (2 Mb/s and 11 Mb/s).
Addressing
All wireless addresses for the meeting are in the 192.35.164.0/22 block.
Checking Out a Card
- Locate the wireless desk; it will be either in the registration
area or the back of the main ballroom.
- We will take a credit card number to ensure timely return of your
card :-) .
- On Tuesday (or earlier if you wish), please
return the cards to the wireless desk in the ballroom (not to the
registration desk.) Your name will be checked off as having turned in
your card, and you're all set. If you lose or damage the card,
your credit card will be charged the price of the wireless card
(approximately $100).
If you already own a wireless card, please feel free to bring it. If you
are thinking about buying a wireless card, you should probably get any
brand of card that offers IEEE 802.11 compliancy. You'll probably want to
get a card that uses Direct Sequence technology, as frequency
hopping has a lower maximum theoretical bandwidth (2Mb/s).
Drivers
If the following
options are availabile in your driver, you'll be best served by
setting:
Drivers are available on-site on CDs provided with some wireless cards,
and on the web:
For help installing your card, ask at the wireless desk or check with
the Merit staff.
Squid Cache 
Take advantage of the NANOG Web cache! Traffic analyses from recent
meetings show that on average, it's approximately twice as
fast to load a page from the cache than from the origin server
directly. In addition to saving bandwidth, caching reduces the load on
the Web sites you're accessing, and gives you lower latency to overseas
hosts.
Follow these steps to configure your browser to
use the cache. The NANOG24 cache uses Squid, a freely available Web
proxy
cache.
The NANOG multicast broadcast is produced by the University of Oregon,
with help from Cisco and Sprint.
To pick up multicast client software see:
- http://videolab.uoregon.edu/download.html
You can test your multicast connectivity here:-

Broadcast Types
- The H.261 broadcast will be visible to all users with
a standard multicast client.
- The MPEG-1 broadcast is generated using IP/TV, a streaming
video server from Cisco. Client tools are available from the University of Oregon
Video Lab.
- The MPEG-4
broadcast will be usable by a small subset of clients.
Session Names
In SDR and iptvhost.uoregon.edu the session names will be:
- NANOG 28 (H.261)
- NANOG 28 (MPEG1)
- NANOG 28 (MPEG4)
If you're not using SDR, the session information will be:
- H.261
- video - 224.2.190.103:61180
- audio - 224.2.244.203:16594
- MPEG1
- video - 224.2.243.37:52390

Feedback or questions about the multicast sessions can be
sent to multicast@lists.uoregon.edu
NANOG 28 is also being broadcast with RealNetwork's RealServer 8.0. To
view the live or archived feeds, you can use RealPlayer
5.0 and above. To watch the meeting live, check the links on the main conference page. If you have questions about
the Real Media broadcast, check with the Merit staff or send e-mail to
nanog-support@nanog.org.
IPv6
All NANOG wireless and terrestrial ethernet ports will be IPv4/IPv6-ready.
The NANOG conference site will have native IPv6 connectivity via
Abilene/Internet2, in cooperation with the University of Utah. You'll want to use IPv6
stateless address autoconfiguration (RFC2462).
We do not provide static IPv6 addresses.
IPv6 implementations for various laptop platforms are available from ipv6.org. If you
have questions about v6 connectivity, please check with a Merit/NANOG
staff member or send email to nanog-support@nanog.org.
DHCP
These graphs show information
from the
NANOG DHCP server. The first graph shows the number of IP addresses
assigned and the number of MAC addresses making DHCP requests. The
second graph shows the rate at which addresses are assigned.
