Well,
Today i found something out....
some how my 5 ip block was removed from my account around 4 months ago ( so free yay lol )
But here is the thing, i have still been using my ips and all no issues for those 4 months.
So for some free statics do this.
1. Get your public IP. type "my ip" in google. This will be your default gateway!
2. in CMD type ipconfig /all and get your DNS servers.
3. Now this is the ish part. to find the right IP.
Lets say your routers IP is 70.211.192.250 Then you should probably try
70.211.192.245 thought 249. For this one you can use the subnet mask 255.255.255.248 ( change the subnet mask depending on the range your working with of course )
4. Go in to your network config and put in all the information you have gathered.
Example:
hit OK and test it out!
let me know how well it works for you works for me fine!
