Mobile Broadband - Does This Have A Static or Dynamic IP Address?

N/A
Hi I just have a small issue I'd like to get cleared up.

I would like to know if the vodafone mobile broadband package comes with a static or dynamic Ip address?

Take for example the starter package at £15 a month.

With the USB modem stick would I be assigned a new IP address every time I detach the USB stick from my PC?

In other words if I went to check my IP address before the removal, then after the IP address would be different.

I went to speak to someone at a vodafone store earlier in the day, they said the IP address would remain the same, but I'd just like a second opinion on this.

Thanks in advance.

Hi greasy

Thanks for the new post :)

I've checked this out for you just to make sure my information was correct before I answered.

For the Mobile Broadband we actually use a range of IP addresses.

This would mean that you could be allocated a different one to your previous connection.

Here is the range that we use:-

212.183.140.48/28
212.183.140.102/31
212.183.140.16/28
212.183.140.98/31
212.183.140.32/28
212.183.140.100/31
212.183.140.0/28
212.183.140.96/31

I trust this answers your question.

Many Thanks

Thanks for your reply. So it is dynamic... however the new IP we will be assigned will always be one of the listed IP addresses?

You will be lucky if you keep same IP address during any dialup connection to internet.

Forget about checking your outgoing IP address as although you will receive correct IP for that
particular outgoing connection, your next outgoing connection (from same dialup) might well
be from a different IP address. I have made connections back to a system where I can see
the source IP and seen periods when my outgoing IP address has remained the same for different
connections but other times they change. There are also different outgoing IP address ranges
depending on service, ports 25 and 80 each having their own different IP blocks.

So not static, and worse than fixed for session dynamic, so what's the problem you want to solve?
