Hi, 

We are deploying 5 x computer terminals across the airport and cannot use the companies network for internet access and therefore have to use a 4G data connection. But how we secure the connection to the computer terminals is by whitelisting their IP address. So i have two questions about your 4G connection.

1. Are we able to have a static IP address on a 4G vodem/mobile hotspot?

2. How often does an IP address change on a 4G vodem, if we stay in one location and don't disconnect i'd assume that we would have the same IP address?

Thanks,

Jarrod Lodge

Thanks for your post.

1. No

2. Yes

The IP is dyncamically assigned but if you don't disconnect then it will stay the same.

The standard ‘vodafone’ APN is CG-NAT’d , hence the equipment would not have a externally reachable public IP. Not a good idea to be whitelisting the IP assigned as it would be in use by multiple subscribers at the same time.

Really for what you want to achieve, you’d need a private APN , and with a private APN you would be able to assigned static IP’s to each connection also.

Cheers.

Spark have just recently released a 4G plan with static IP address. Could be worth looking in to.
