IP address'

I fell into the fights and flame wars page and read a few posts allegedly written by the w@nker formerly known as TGE*mumble something or other*.

If you (admin/korn/otherwise) ban's an IP address, surely the offender just has to reconnect to the internet to get a different IP?

I have broadband which is never turned off at the wall, so even if I turn off or re-boot my PC it keeps the same IP address. If we had a power cut or I turned the cable modem off, then it re-assigns a new IP.

Doesn't it?

Im confused.

Dialup internet connection users are assigned a new IP each time they connect. However it is possible to ban an entire ISP or IP range if needed (each ISP has a different range of IP address to asign to people as they connect)

Your broadband might have a static IP, so even when you re-connect you'll have the same IP. However you normally have to specify this when you join with your ISP and sometimes pay extra for it. There aren't any real advantages for a home user in having it.

Most broadband connections get a new IP each time you connect Smile

Hope that makes some sort of sense Smile

I find ntl IP addresses are static for a few months, but do change.

So you can't be 100% sure on such things.

I've not read the above, cos i'm lazy like that, but you only get a static IP if you pay your ISP for one (even though it's a simple case of ticking a box for them!)
I'm on virgin.net adsl and do get a different IP each time i connect-but i've got a broadband router which keeps the connection alive.
My IP does stay the same as i never disconnect, even when no computers require the connection.
This is a much simpler way of networking multiple PC's and sharing the internet.

You can also pay some ISP's for up to 4 static IP's.
This way you can use NAT (Network Address Translation) and give each PC on the network an internet IP address - as if each computer had their own modem.

Hope this helps

Actually, they don't all use a static IP, as for each IP they purchase it costs them money, so they'd have to buy more if they give everyone one. Not everyone is connected to thier internet connection 24 hours a day (I havn't figured out how to do this yet Sad

) so they don't have to buy as many IP's as they have customers.

Thats the connection ratio, which for ADSL is about 20:1 or 50:1 for most home connections meaning they've got 50 customers for each IP.

There's also the issue that the world is running out of IP addresses, hence the move to IPv6. Once that gets going people will probably be throwing static IPs at you. Your computer will have one, your printer, your fridge...

Ponder.

If you connect via a router, wouldn't that hold the IP for you, as you'd be connected (as long as its powered)?

I know then you have to deal with network IPs and all that then, but if I wanted a static IP jobby, wouldn't a DSL router do it?

Most routers will disconnect after a set amount of time of inactivity. There's a setting on mine to change that Smile

I've now got more time to read it as i'm not busy at work with the boss able to see my screen.
Me saying I'm lazy just means I'm too lazy to say why i didn't read it Razz

NTl do use DHCP but if you run the little program called New IP on the cd they give ya you can get the server to re-assign you a new one ( usefully if you have errr been doing silly illegal things) but generally you will keep the same ip for a while like G said as temp address.
