I've got an old connection log to a website which contains the IP addresses, the user agent string and the timestamp. I want to know how many of them used 3G to access a website as I suspect there is a latency issue.

Now I know that I can use some code to have this info directly from the user.

But I still want to process this old log using only IP addresses even if it is only for one ISP.

I thought I could do that by finding a list of the subnets used for 3g.

Do you think it can be done? Otherwise, what do you suggest?

Hope you can help. Cheers,

Toll

One approach could be to lookup every IP using "whois" services, if the ISP listed is a phone carrier only, you can be certain the connection was made by a mobile connection.

This is not a total solution, but it might give you enough information.

Now, to find a service which will allow you to make all the requests required, might be another matter.
