Was trying to determine where this 'honolulu' speedtest was hosted:

Tracing route to honolulu.speedtest.net [74.209.160.12] over a maximum of 30 hops: 1 22 ms * * 123.87.93.224 2 27 ms 29 ms 25 ms hawaiian-telcom-inc.gigabitethernet2-17.core1.lax2.he.net [184.105.134.170] 3 84 ms 90 ms 84 ms gige-g2-17.core1.lax2.he.net [184.105.134.169] 4 92 ms 98 ms 99 ms 10gigabitethernet7-3.core1.sjc2.he.net [184.105.213.5] 5 112 ms 114 ms 112 ms 10gigabitethernet4-3.core1.sea1.he.net [72.52.92.158] 6 113 ms 113 ms 114 ms six.netriver.net [206.81.80.160] 7 113 ms 113 ms 113 ms static-74-209-160-12.lynnwood.netriver.net [74.209.160.12] Trace complete.

123.87.93.224?

inetnum: 123.64.0.0 - 123.95.255.255 netname: CTTNET country: CN descr: China TieTong Telecommunications Corporation

Well, the DNS name is for a colocation facility in Lynnwood, WA via the Seattle Internet Exchange. I can confirm that the 6th hop actually does traverse the SIX, in as much as that IP is correct.

Mike

Thanks. What concerned me was the first hop...22ms. is ~ the distance from Maui to Oahu, but why the Chinese IP? Cruel joke? I"m using Hawaiian Telcom's ADSL service and that first hop has always been their gateway IP address. Another TCP trace shows the first hop as 123.74.62.128...another CN address.

I'm assuming your provider's network engineers (stupidly) assumed 123.x.x.x was a good idea for use in a private setup because it hadn't been assigned from the global pool (yet).

Wouldn't be the first provider or service to not use proper RFC assigned private IP space for their internal networking setup.

Well, in the 7-8 years I've been with them, they've never used Private IP space. IPConfig shows: Connection-specific DNS Suffix . : hawaiiantel.net Description . . . . . . . . . . . : CNet PRO200WL PCI Fast Ethernet Adapter Physical Address. . . . . . . . . : 00-08-A1-01-0E-29 Dhcp Enabled. . . . . . . . . . . : Yes Autoconfiguration Enabled . . . . : Yes IP Address. . . . . . . . . . . . : 72.234.20x.x Subnet Mask . . . . . . . . . . . : 255.255.254.0 Default Gateway . . . . . . . . . : 72.234.206.1 DHCP Server . . . . . . . . . . . : 72.235.80.4 DNS Servers . . . . . . . . . . . : 72.235.80.12 72.235.80.4

They are testing IPTV on Oahu in preperation for roll-out, so maybe they renumbered in order to more easily identify the segments.(?)

by squating on address space that is or will be in use. joel

I was about to reply pointing that out. FWIW, they're not announcing that space, so I definitely agree with the poorly-thought-out private infrastructure theory. http://bgp.he.net/AS36149#_prefixes FWIW.

Poorly thought out private IP space? Nah...it's part of their security measures. It keeps those pesky Chinese from communicating with their network.
