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 would end up with a PTR record of

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
