Summary

IP network services and terminal room are available 24 hours a day during the meeting (from Sunday, February 29 at 12 noon to Friday, March 5 at 12 noon). Brief diagram of the network is available here.

Onyx (formally called Gardenia) A1 on the 2nd floor, near the escalators, is set up as the terminal room. The terminal room provides wireless and wired connectivity, AC outlets, two printers, 20 Windows XP based notebooks for public use and helpdesk.

For Wireless, 802.11a/b access points are located throughout the hotel. In-room access is provided by the hotel and not administered by IETF59 NOC.

No firewalls are installed between IETF59 network and the outside world. Access to multicast is available from the wired network only.

Korea use 220V AC, 60Hz power. Power outlets are compatible with European plugs just like those you used in Munich and Oslo.

Helpdesk

Helpdesk is located inside the terminal room. Staffed hours are from 8am till 10pm. Emergency phone number will be posted during the non-staffed hours. To report trouble, please send your mails to 59crew@noc.kr.apan.net.

Security Warning

Never use protocols that use cleartext passwords (such as telnet or non-APOP POP3). Instead, please use encrypted protocols such as SSH, SSL or IPsec. It is well-known that people may be sniffing packets on the network as there is no layer 2 protection povided for the IETF59 network.

Address Blocks

218.37.192.0/18
2001:220:101A::/48

DHCP is provided for IPv4, and dynamic autoconfiguration is used for IPv6.

If you need static IPv4 addresses, please inform via email at ietf59-static@noc.kr.apan.net. Your request should contain the following information. Name, Email, Number of v4 addresses required, and type(wired, wireless or both). You can also get the static assignments from the helpdesk onsite.

Wireless

802.11a/b network is available. Advertised SSID is "ietf59". No double quotes.

Statistics on wireless usage is available here.

Most areas of levels 1, 2, 3, 36 and 37 are covered. La Seinne(Buffet restaurant) and Bobby London(Pub) in B1 level are also covered.

*Warning* 802.11a users should set country selection to "US". Due to regulatory/market issues, there are virtually no 802.11a users in Korea and all of IETF59 access points are configured to use US bands.

*Warning* You MUST NOT enable "ad-hoc" modes from your clients. MacOS users, you MUST NOT use "Create Network..." from your Airport setup.

*Warning* Wireless access from guest rooms are not provided by the IETF59 NOC, but provided by the hotel with SSID "LotteHotel". We regret that we were unable to negotiate with the hotel for possible switchover of guest room wireless into IETF59 network.

IPv6

Access to global IPv6 network is provided to wired and wireless subnets. Please use dynamic auto configuration.

Public Terminals

There are a total of 20 laptop computers for attendees' use in the terminal room. All of them are running Windows XP and have Putty SSH client, Office suite, and Cygwin installed.

Servers

DNS

218.37.196.21, 218.37.196.22 (DHCP will let you know)
2001:220:101A:196::21, 2001:220:101A:196::22

IETF59 network provides dynamic DNS update capability on experimental basis with IPv4 addresses obtained by DHCP. If your laptop has a FQDN, then the FQDN is registered in the inverse zone of IETF59. If your laptop has a non-FQDN hostname, it's registered in both the regular and inverse zones.
