[dns-operations] PTR Records for Broadband Network?

>From my understanding some of these companies assume that ALL our IP blocks are used for hosting and that traffic from them is from VPNs or is in some way illegitimate.
We have tried repeatedly to engage with the various companies, but a lot of them don’t have a public contact for their network or security team, so our clients end up having to deal with their first level customer service teams. In the case of Disney+, for example, their CS team can resolve the issue on a per IP basis, but that obviously does not scale. Netflix does seem to be responsive thankfully, but others like Ticketmaster and All4 are a black box.
We honestly do not know what it is that they are looking for. In the description field for our broadband IPs we try to make it clear that they’re being used for broaband and not hosting:

inetnum:        185.97.236.0 - 185.97.236.255
netname:        BLACKNIGHT-BROADBAND
descr:          Broadband Customers

So we are trying to tweak what we can tweak ie. That which we control in the hope that it has some impact.


Regards

Michele

Hi Michele.
Before changing anything, exactly what problem is it that Disney+ etc. are having? Or better, what do they *expect* to see, if not what you have now?
I didn't think many people used PTR records.

Cheers, Greg

All

Sorry if this is a little left of field, but I suspect that collectively the people on this list can give us better advice than many.

Many many moons ago we setup the PTR records for our network using a template that clearly flagged that the IPs were static and used for hosting.

The result was that the IP 185.97.239.13 would end up with a PTR record of 239-13.colo.sta.blacknight.ie<http://239-13.colo.sta.blacknight.ie>

Fast forward to 2022 and we now offer broadband to both businesses and consumers, but unfortunately some streaming services and others are blocking access. So our users have issues with Disney+, All4, Netflix and Ticketmaster to name but a few examples. One of the issues appears to be the PTR records.

For clarity the IP blocks we use for broadband are NOT the same blocks that we use for hosting.

We are therefore looking at tweaking the PTR records for the broadband net blocks.

Would removing the “colo.sta” bit be enough?

Should we replace it with something else?

Thanks and regards

Michele
