How to Report bad IP address

Hi,

 

How do I report a bad IP address, in order to stop it's re-assignment from the dhcp pool?

The IP address I have currently been assigned by BT appears on various IP black lists. For example when accessing the National Lottery site the connection attemp just hangs. A Tracert test gives:

 

C:\Users\Administrator>tracert www.national-lotter.co.uk

 

Tracing route to www.national-lotter.co.uk [98.124.198.1]
over a maximum of 30 hops:

 

1 1 ms <1 ms <1 ms BThomehub.home [192.168.1.254]

30 * * * Request timed out.

Trace complete.

 

As can be seen the traffic is routed to Prolexic. A company specializing in web site anti DDOS protection. Looks like my IP has been flagged as one used in the past for questionable activities. I understand that by just simply rebooting the modem I'm likely to be assigned another IP, but I want to get this bad IP removed from the pool so it doesn't get re-assigned to someone else. Experience in the past has shown that there is likely to be little success to tiring to get the IP removed from the blacklist at Prolexic's end. That would need more clout than a home user processes. 

So how do I report to this bad address to BT ?

 

Kind Regards

Gary

Re: How to Report bad IP address

Seems like this IP is blacklisted on the following:

SORBS DUHL, Spamhaus ZEN & SEM BLACK

 

Tried rebooting the modem and just got the same IP 😞

 

Anyone help?

Re: How to Report bad IP address

I would try another reset but disconnect for couple of minutes before reconnecting and that should be enough to get a new IP address

Re: How to Report bad IP address

Thanks, left it a bit longer and IP now changed.

Doesn't help the next person who gets IP though. There must be a BT process for dealing with blacklisted IP's. I've applied to de-list the IP on one of the three above but the other two require reqests from IP block range holders (ie BT).
