Hello World
Some of our customer within our 31.11.0.0/19 allocation, get blocked while trying to access streaming content from drs.ch, bluewin.ch and iTunes, because somehow those sites think they are located outside switzerland. (I suppose it mainly affects content hosted as srf.ch)
http://www.ipaddresslabs.com and http://www.maxmind.com
Do locate the ip addresses correctly to switzerland.
So I suppose SRF uses some other service.
Does somebody know what GeoIP Locator services srf.ch uses? The SRF IT Helpdesk was not able to tell me.
Kind regards
Benoit Panizzon
Hi Benoit,
Can`t say for sure how srf do it but in most cases this is done based on internet registry queries (RIPE db for example). Maybe you checked this already but it is possible that the specific IPs having the issue are not directly related to the /19 you mentionned but to a smaller more specific subnet which is assigned to a different country (or was recently as most of these applications do not make real time queries and only synchronise from time to time). Could you possibly provide one or two of the impacted IPs to see if they are part of the /19 or a smaller subnet?
In addition to this I also read that some content providers perform more checks on top of the IP layer, for example related to browser or media application settings, at this level only srf can give you more details. Anyway in my experience similar problems were almost always related to the subnet information in the internet registry...
Regards, Fadi

hey... :-)
I can only speak for the SRF radio streams which are distributed by Init7. Most, actually almost all of them, don't have any geolocation based blocking.

The Problem was solved. They use an offline version of the wipmania.com GeoIP Database. They added our range to their offline database and we have also submitted the range to wipmania.com as it was flagged 'unknown'.
I wasn't aware of WIPmania. It doesn't look too promising though, as they claim on there website:
25 Mai 2011 - Letzte Änderung der WorldIP Datenbank
added or changed 8140 networks 100.749.550 IP addresses changed total 91423 networks
37.17.232.0/21 which was recently allocated to Init7 Germany is also missing, for example. I submitted this range now. It seems that WIPmania is not importing new allocation automatically.
Large blocks such as 37.50.0.0/15 and 37.80.0.0/12 which have been allocated to T-Mobile three days ago should appear immediately, or at least as soon as they show up in the routing table.
