Whats your internetcompany?
Cause Static Ip is normaly only for Companys or Buisness users and you have to pay extra money for it.
And those guys who told u to use V.P.N. thats bullshit cause it masked only the IP at the PRIVAT "name says everiting" Network.
At your Privat network u can have an Static IP thats no Problem.
But the adress to your Inet Company shoult be changed and thats not possible with an V.P.N. Tool.
Problem is if u use an V.P.N. the adress between Company and your modem is still the same.
If blizz track the ip back the get the v.p.n. ip then the ip between internetcompany and modem and your privat ip.
10 hours is not long enough, try 24 hours + i know its hard lol. trust me it took me over a month to decide to finally leave my modem off and that was when i took my computer in to get some upgrades.
