PlusNet IP ranges

[#1]

Hi,
As part of my paranoia I monitor the IP address I am given on each startup. So far (about 3 years) it has always started with 87. but on Wednesday 1st Dec it changed to 91.125.***.***. Doing a tracert I found this was a bona fide PlusNet IP.
Do PlusNet publish their DHCP ranges ?
Thanks
Peter

Hi Peterworks,
It's not something we publish, not particular reason for that AFAIK but the 91. ip addresses are one we've recently reclaimed from our brightview network.

Thanks JoJo for your quick response.
Do PN use the whole 91 range ?
Also, in this day and age of trying to safeguard ourselves from 'them', would it not be fairly easy to publish your DHCP ranges ? I'm not sure how other PN users would view this but I would find it very comforting from a security point of view.
Regards,
Peter

The DHCP range is publicly available via leaked databases of our IP addresses, you just have to decipher the start and endpoint of the range, but it should be easy given the amount of IP's that were leaked from Plusnet and ACS.

It's not a database, it's a couple of spreadsheets. Given the relatively small number of entries on it as well it almost certainly doesn't include all of our ranges.
For the benefit of the OP/others, I think this covers most of them:

80.189.0.0/16
91.125.0.0/16 
195.166.128.0/19
212.56.64.0/18
212.159.0.0/17
81.174.128.0/17
80.229.0.0/16
84.92.0.0/15
87.112.0.0/14
46.208.0.0/16

Is it at all possible to request a specific ip from one of those ranges when using static?

Have a look at this page. I think it answers your question.

Thanks again to Joanne Pilson, foxtrck, Bob Pullen and dratdestroyer.
Although these responses help a great deal I would have thought PN should have a definitive list and, as Joanne Pilson says, there should be no reason why this cannot be published. I would imagine the PN engineers would need to be aware of them all anyway and, as such, they would be documented.

They are documented. That's what I posted. The IPs are in CIDR notation.

Bob,
Sorry I misunderstood you as you said "I think this covers most of them:"
I will take this as the definitive list.
Thanks
Peter
