IP OSM not listed - API? - Qlikview

Hello Guys,

I am trying to make it work an application that I developed with an object extension for Qlikview, that uses OSM. I am not sure, I think this is some sort of an API...

Problem is, I have the servers IP address in the wiki page, but, my application goes to this IP address: "140.211.15.75"

I get back this information:

140.211.15.75 IP address location & more: 
IP address [?]: 140.211.15.75 [Copy][Whois] [Reverse IP]  
IP country code: US 
IP address country:  United States 
IP address state: Oregon 
IP address city: Eugene 
IP postcode: 97403 
IP address latitude: 44.0364 
IP address longitude: -123.0547 
ISP of this IP [?]: Oregon State System of Higher Education 
Organization: Oregon State System of Higher Education 
Host of this IP: [?]: projects.osgeo.osuosl.org [Whois] [Trace]  
Local time in United States: 2014-03-25 11:19

So, I got an IP Address that is not listed in the OSM Server list (http://wiki.openstreetmap.org/wiki/Server)

Why did I get this IP? And, is there any other IP that I should unblock??? Is there a list somewhere that I should unblock in my firewall?

Since now, thank you.
