En analyse af rigtigheden af de oplysninger om placeringen af udgangsservere, der blev angivet af VPN-udbydere, er blevet foretaget. Af de 20 testede VPN-udbydere angav kun 3 altid korrekte oplysninger om de lande, hvor de udgangsservere befinder sig. 6 udbydere gav virtuelle (uunderbyggede ved kontrol) eller usikre (lande, hvor der ikke blev registreret trafik) oplysninger om landet i mere end 50% af tilf\u00e6ldene, mens 3 udbydere - mellem 30% og 49%. Nogle h\u00e6vdede at have udstyr placeret i mere end 100 lande, men sendte faktisk trafik fra et par datacentre i USA og Europa. <\/p>\n

I alt blev der analyseret mere end 150.000 udgangs-IP-adresser, if\u00f8lge erkl\u00e6ringen VPN<\/a>-udbydere der d\u00e6kker 137 lande. Kontrollen blev udf\u00f8rt ved at analysere ruting, RTT (round-trip time) og forsinkelser ved pakkeoverf\u00f8rsel. Oplysningerne om landet var ikke i overensstemmelse med virkeligheden for cirka 8.000 IP-adresser<\/a> udgangsnoder. Uoverensstemmelsen mellem det angivne og det faktiske land kunne n\u00e5 op til flere tusinde kilometer. 38 angivne lande viste sig at v\u00e6re virtuelle, og der blev ikke registreret trafik fra dem. <\/p>\n

En af \u00e5rsagerne til uoverensstemmelsen i oplysningerne er un\u00f8jagtigheder i Whois og databaserne for registratorer. Problemet er, at data i s\u00e5danne databaser indtastes baseret p\u00e5 registreringen af ejere af IP-adresser og de oplysninger, de videregiver. Oplysningerne bliver ikke verificeret, s\u00e5 der kan opst\u00e5 situationer, hvor et firma videregiver forkert information om placeringen, ikke opdaterer for\u00e6ldede data eller er registreret i et land, mens udstyret er placeret i et andet. Der stilles ogs\u00e5 sp\u00f8rgsm\u00e5l ved rigtigheden af oplysningerne i GeoIP-tjenester som MaxMind, IP2Location og Digital Element, som h\u00e6vder pr\u00e6cisionsprocenter p\u00e5 99,5-99,9% uden faktisk at verificere placeringen.
