surfisup1000: Thanks for the answer -- this is not really a suitable solution as I like to reboot my modem once a day to avoid becoming a sitting target for hackers. Maybe paranoid but I'd been hacked before.

This makes no difference at all as most tools used are network scanners that can go through IP blocks in minutes and if you change or not it will make no difference.

This is a false sense of security.

ISPs need to start selling Carrier Grade NAT as a premium feature. Great for hiding from the Skynet law ;)

johnr: Why do you need a new IP address?

There are several reasons.

First is security, I like that my machine changes IP occasionally. Once I noticed a lot of connections coming into my system and was able to change ip to get away from this.

Another one is some download websites limit you by your IP address. Changing is a quick way around this restriction.

I wonder why they changed this? I'd have thought with ip addresses becoming scarce that telecom would not want to tie them all up on static allocations.

However, from the above comments I guess it is not possible anymore (didn't telecom make you pay for static IP's in the past?).

this means when you torrent, you could end up getting an innocent old lady being fined for illegal downloading!

it's not altogether false. if someone is randomly port scanning lots of ip addresses they're likely to be blocked pretty quickly. some isps already block some ports like port 445.

i got hacked once before, but it was on a virtual server i'd just signed up to, and i was using a temporary dictionary based password.

generally if you're going to allow access to services from the world you must have complex passwords, and not simple things like

word123

as most people have a password then a number, it's actually higher security to have 123word. it's also not helpful to have a password like w0rd or p@ssw0rd.

of course a lot of places to get virtual servers on the internet email you your password, so it can still make sense to use an unimportant password and change it. in the end they just seemed to try joining my server up to some botnet over irc. it was quickly killed, and i just reimaged.

with xtra's normal dynamic ip's if you connect 4 times you'll often end up with 4 completely different ip's... one 219.. one 210... one 202... etc etc.

and i do like that they've fixed this. as it's damn annoying when you have adsl decide to reconnnect then the ip changes and you use lose all of your existing connections.

Possibly. Maybe it is not the best reason but there were other reasons too.

A good example is the telegraph.co.uk website.

They only allow you to view a few articles before shutting your IP out. Previously, i could change IP and bypass that restriction.

I'm certainly not going to pay for a subscription to a UK online news site.
