Getting a new IP address?

Jelly · 31-07-2008, 21:58

I appear to have annoyed an Internet Tough-guy to the point where he is threatening to either DDoS or DoS me. I'm fairly sure he doesn't know the difference and that these are empty threats, but for safety concerns I'm considering changing my IP, since he has my current one.

As far as I know, Virgin customers have Dynamic IPs that change every now and then, but I'm wondering if I can do it manually. Is it a case of ipconfig \release, ipconfig \renew, or do I need to unplug the modem for a while?

Thanks for any help.

I've just updated it, let's hope a mod approves it

if so, then you'll want to be reading the last post made in that thread.

You may just be passing the problem on to somebody else that might get your released IP..

If its a forum user an admin will be able to identify their IP address, if its via instant messaging a netstat command will probably identify the IP address they are using.

There are ways to get IP addresses, the net is not as safe and anonymous as people think.

I tend to route my email through google these days for news letters and stuff like that, if somebody wants to waste googles bandwith then as far as I am concerned they can feel free

they aren't used for a while, so i'm sure they'd give up

(especially when it's nulled)

DHCP is quite clever.

Once a IP address has been reconciled as free in the DB its fair game is my understanding.

Depending on how many IP's there are in the scope would probably determine how often they could get used.

i'm quite aware of what DHCP can and can't do. it's held back *really*. nice effort though.

I'm unaware of the lease duration on Virgins DHCP servers but assuming the original DHCP client has not gone through the re-newall process that IP address is available at lease expiration

Unless you know differant?

Perhaps I should go back to my old RFC's

once an IP address has gone past expiration, regardless of whether it was automatic or forced.. it's not provisioned to some customer down the road in the next 20 minutes. if you want more information, DOCSIS and DHCP might be of a good read.

At 21 mins then? At what point on Virgins network is it available for reissue?

I prefer to read the RFC's they are a pretty good read too, amazing how many ISP's dont actually follow them.

I've tried to do it a few times, and I'm able to get a new IP. However, when I reconnect the router, I can't access the internet. If I reset the modem, the Internet will work again, but my old IP has returned.
