Interesting Internet access at a holiday park / 2011-09-11

The Internet access offering in our holiday park is quite special:

RFC1918, collect the whole set:

traceroute to koos (xx.xx.xx.xx), 30 hops max, 60 byte packets
 1  firstspot.org (10.85.192.11)  15.912 ms  15.886 ms  15.858 ms
 2  172.16.0.1 (172.16.0.1)  16.633 ms  17.240 ms  17.866 ms

 4  nl-asd-dc2-ias-ard30.kpn.net (62.12.4.72)  34.213 ms  35.957 ms  37.628 ms

This suggests 3 layers of NAT, but I'm not sure. Network seen at a holiday park. 192.168.1.254 seems to be a thomson product (adsl router?), 172.16.0.1 some edimax router. Firstspot is a captive portal for wireless networks (although the network is used wired here): Firstspot captive portal.

Interesting conditions according to the captive portal for this wired network in the Netherlands:

I. GENERAL TERMS AND CONDITIONS APPLICABLE TO Sternpixel B.V\\\'S WIRELESS DATA SERVICES, INCLUDING BUT NOT LIMITED TO, FEATURES THAT MAY BE USED WITH WIRELESS DATA SERVICES AND WIRELESS CONTENT. General Requirements: SternPixel B.V provides wireless data services, including but not limited to, features that may be used with wireless data services and wireless content and applications (\"Services\"). The absolute capacity of the wireless data network is limited. Accordingly, service is only provided for prescribed purposes and pricing for Data Services is device dependent and based on the transmit and receive capacity of each device. A pricing plan designated for one type of device may not be used with another device. Some devices or plans may require you to subscribe to both a voice and a data plan. If SternPixel L B.V determines that you are not subscribed to the required plan(s), SternPixel B.V reserves the right to switch you to the required plan or plans and bill you the appropriate monthly fee. The Services may be subject to credit approval. An activation fee of up to $36 may apply to each new data line. Compatible data-enabled wireless device required. Usage/Billing: Usage and monthly fees will be billed as specified in your rate plan brochure, customer service summary, or rate plan information online. DATA TRANSPORT IS CALCULATED IN FULL-KILOBYTE (\\\\\\\\\\\\\\\"KB\\\\\\\\\\\\\\\") INCREMENTS, AND ACTUAL TRANSPORT IS ROUNDED UP TO THE NEXT FULL KB INCREMENT AT THE END OF EACH DATA SESSION FOR BILLING PURPOSES. TRANSPORT IS BILLED EITHER BY THE KB OR MEGABYTE (\"MB\"). IF BILLED BY MB, THE FULL KBs CALCULATED FOR EACH DATA SESSION DURING THE BILLING PERIOD ARE TOTALED AND ROUNDED UP TO NEXT FULL MB INCREMENT TO DETERMINE BILLING. IF BILLED BY KB, THE FULL KBs CALCULATED FOR EACH DATA SESSION DURING THE BILLING PERIOD ARE TOTALED TO DETERMINE BILLING. NETWORK OVERHEAD, SOFTWARE UPDATE REQUESTS, AND RESEND REQUESTS CAUSED BY NETWORK ERRORS CAN INCREASE MEASURED KILOBYTES. AIRTIME AND OTHER MEASURED USAGE ARE BILLED IN FULL-MINUTE INCREMENTS AND ROUNDED UP TO THE NEXT FULL-MINUTE INCREMENT AT THE END OF EACH CALL FOR BILLING PURPOSES. Data sent and received includes, but is not limited to downloads, email, overhead and software update checks. Unless designated for International or Canada use, prices and included use apply to EDGE/GPRS and BroadbandConnect access and use on sternpixel B.V\'s wireless network and its affiliated partner wireless networks within the United States and its territories (Puerto Rico and the U.S. Virgin Islands), excluding areas within the Gulf of Mexico. Usage on networks not owned by sternpixel B.V is limited as provided in your data plan. Charges will be based on the location of the site receiving and transmitting service and not the location of the subscriber. BroadBandConnect access requires a compatible, eligible 3G device. Unless otherwise specified, overage is billed either by the KB or MB. Service charges paid in advance for monthly or annual Services are nonrefundable. Some Services may require an additional monthly subscription fee and/or be subject to additional charges and restrictions. See applicable rate plan materials for complete pricing and terms. Prices do not include taxes, directory assistance, roaming, universal services fees or other exactions and are subject to change. In order to assess your usage during an applicable billing period, you may obtain approximate usage information by calling customer service or using one of our automated systems.

Wireless device? Prices in dollars? GPRS? Edge? 3G? Wireless network? Use within the United States of America? All terms which do not apply to this network, which makes these terms and conditions very worthless.
