After having several days of good speeds since I got my line problems sorted out thanks to the great folks here at MyBB, yesterday I had a terrible day. Line so slow on everything and all sorts of Google warnings, email server issues and what not.

Turns out the IP address I got issued by my ISP had been blacklisted due to a previous user abusing it for what not.

It caused just about everything I was doing (including accessing my very own servers) to be nothing short of a nightmare.

Even a Google search would keep giving me a captcha to complete with a warning the they had seen massive connections from my IP .... well not from me .... from the abuser who had it before me.

So I do think it's something to add into the checklist of when checking for issues on your ADSL speed.

I have now placed it at the top of my morning checklist now.

I'm assuming everything is better today?, might be malware on your PC have you scanned for viruses yet?. Could also be a middle man attack, where a hacker would hack your connection to make fraudulent transactions, happens a lot. Don't think an ISP will give you a Blacklisted IP address, unless it's a static IP and there's some kind of issue at your ISP.
 
I had a similar issue last week. I found my IP address listed on 3 black lists. Contacted my ISP and it turned out to be (in their words) "A block of IP addresses". Cleared yesterday sometime, okay today. So yes it does happen and it is best if you get your ISP to help sort it out. I appear to have now been given a "static IP address" but I will have to see if this is the case.

Must say my ISP was very helpful in sorting this matter out ....

The link posted by OP is the one I also use to check my IP address.

It was acknowledged by the ISP, and they were very apologetic. Somebody did have the IP prior to me and it was abused and also severely blacklisted. No malware or anything or men hiding in the middle :D First time it's ever happened so obviously somebody found some way of hijacking one of their IP's. I now check my IP every morning regardless and also during the day just to be 100% sure.

Actual IP address assignment to DSL subscribers is handled by Telkom through their IPC infrastructure (specifically by the BRAS if my memory serves me correctly). The ISPs provide Telkom with blocks of their own IP address space for Telkom to provision in this manner.
