It has been a month since I turned in my 188.8.131.52/29 IP address block to Comcast, and 3 weeks since I officially asked for my domain name to be removed from that IP address block that I no longer use (because it was obvious after a week that it wasn't going to be done automatically). And yet, what do still I see?
To make this matter even more ridiculous, it is pretty obvious that Comcast has already assigned that former 184.108.40.206/29 block into 220.127.116.11/30 and 18.104.22.168/30 IP address blocks that are already in use by other customers (as is illustrated by the ping responses shown below).
I don't have any idea what the current users of those IP addresses are doing with their connection, and I really don't care. What I do care about is that whatever is being done, there is the implication that I am doing it because the PTR records point back to one of my domains. And so far the only response I have gotten from Comcast to my request to have the PTR records changed to either point back to the default 75-146-8-4x-Nashville.hfc.comcastbusiness.net values, or point to the new users, is a not so veiled threat from a Comcast legal beagle that I should not be trying to use static IP addresses if I am not paying for them.
EDIT: I almost forgot to mention that one other thing was done as a result of my request to revert the PTR entries to their default values. Within a day of being called by the Comcast legal beagle, my SMCD3G-CCR was remotely issued a factory default reset which took it out of bridge mode. The first BC CSR I spoke to after it happened said that it had been done deliberately (following Comcast management orders) to keep me from trying to illegally use static IP addresses without paying for them, and he refused to help me any further. Now perhaps what that CSR told me was BS because he did not want to admit that he did not know how to put an SMCD3G-CCR into bridge mode, but that was what I was told (and I have never been a big believer in random coincidence).
Fortunately the BC CSR that I spoke to when I called back was more understanding, competent, and cooperative. Of course, my next step was to purchase and install an SB6121 modem, so that any future such retaliation would have minimal effect on my network. FWIW, I purchased the modem because Comcast also refused to let me lease an SB612x modem (I tried to arrange such a swap twice...once at the local Comcast office, and again by contacting Comcast support to try to setup a UPS or FedEx swap).--
We can never have enough of nature.
We need to witness our own limits transgressed, and some life pasturing freely where we never wander.
