The incident I had this morning was a Spark NZ broadband customer, they didn't have a static IP as I asked them to restart their router which gave them a different IP address.
I wouldn't want to unblock them myself as this could cause them to get listed again and more permanently if they hadn't first resolved the cause of it themselves, like you have said.
I imagine, as it was a dynamic address that it would have been blacklisted by another one of Sparks customers beforehand and then dished out to the user I was talking to last night after their office had a power outage.
I've tried looking on the Spark NZ website but could not find any support article or help guide for this scenario.
would anyone on this list (possibly from Spark broadband services) be able to help me with what should be done for this?

Depends who owns the IP space, in the event the ISP has provided space it¹s in your best interest to unblock them so if they get re-assigned to someone else they work.
Again depends on what the customer is doing to continually get blacklisted, I.e. Not fixing an issue they were told to fix, like open NTP or something.
If the IP space belongs to your downstream customer, then it¹s their problem, but still good to try and assist for a quality of service.

Hello all, I'm working for a small web/mail hosting company. I've recently noticed a lot of blacklisted IP addresses from NZ based ISPs being dished out, part of our intrusion prevention methods involve denying connections from these addresses.
How do these blacklisted IP addresses get unlisted? Is it the responsibility of the customers of these ISPs or it is the responsibility of the ISP?
