10.4.0.1 VS 10.7.0.1

[C7Q8 0]

I connect to AirVPN using OpenVPN from command line.

 

$ sudo openvpn --config foo.ovpn

 

I'm using ubuntu 16 with the latest version of OpenVPN. Sometimes OpenVPN creates a tun0 interface on 10.4.0.1 and other times it's 10.7.0.1. I think I've seen it on other 10.*.0.1 addresses before, but I'm not positive at the moment.

 

1. How are these addresses automatically assigned?

 

2. My /etc/resolv.conf is using the 10.4.0.1 nameserver. Should I change my nameserver to 10.7.0.1 when openvpn creates tun0 on that address? Should the nameserver in resolv.conf always match the tun0 address?

 

3. Can I manually force all future ovpn connections to use 10.4.0.1? If yes, how?

 

Thanks

Hi,

 

1. See here.

 

2. You needn't do anything manually. Just make sure the VPN server is also the DNS server using IPLeak.

 

3. All 10.x.0.1 addresses actually point to the same server so it's unnecessary.
