Re: Reverse DNS Request

Hello.  I can't beleive I have to wait until Monday morning to get my reverse DNS corrected???  This should have been setup when I received my static IP addresses.

 

I also think there should be an automated system to set these up.  Lastly, I've had a heck of a time trying to get into the support center for business customers.  It keeps transferring me to the residential site and wants me to reboot my modem.  On top of that, it asks for my social that I've never given and then tries to hang up on me.  Once I got a live person, they didn't know what a PTR record, reverse DNS entry was, etc.  Comcast is really good at automating the voice system, why not automate this as well???  I'm kidding.

 

Please have someone contact me at my business phone number ASAP.

 

Thank you,

 

Jerry

Re: Reverse DNS Request

This is exactly why I want my PTRs delegated.  I don't want to have to contact Comcast more than once.  Setting up PTR delegation is a one time operation and then Comcast never has to handle another request from me for changing PTRs.  I fail to see why Comcast does not see the business sense in a common and ordinary ISP function as reverse DNS delegation.

Re: Reverse DNS Request

I agree with others.  There should be an automated system to add/change/delete reverse dns requests and others related to static IPs.  At a minimum, when the statics are provisioned, comcast should ask if RDNS is needed.  I had forgotten about it and now my email servers are throwing all kinds of errors and my email are backing up.  I can change the address back to ATT for a while but that is counterproductive.

 

Thanks,

 

Jerry

Re: Reverse DNS Request

I don't understand your comment about 24/7.  I called twice on Saturday and when I finally got through to someone they said I had to wait until Monday because they were closed on the weekends.  So that is clearly not 24x7 support.

 

I then called and spoke to three different people today and though I gave them my information, none of them can make the ptr record change.  I then sent a PM to Michelle at comcast and I've only now received a note that my changes are made.  I checked them a few minutes ago an they still aren't active.

Re: Reverse DNS Request

I don't understand How comcast handles the RDNS request, I have been waiting for months for a response from comcast tech. It's really frustrated with Comcast support.

Re: Reverse DNS Request

I too have been extremely displeased and unimpressed with Comcast's ability to handle reverse DNS delegation requests.  If a Comcast Business customer gets a /28 allocation of IP addresses, it's a good chance that the customer is also capable of---and in fact highly likely that they will want---reverse DNS delegation setup, and not want to call Comcast to change PTR records everytime they need a change.

Re: Reverse DNS Request

Thanks so much for taking the time to reach out to us through our business forums regarding RDNS support.  I very much appreciate your patience and greatly apologize for the delay in our response. Thanks so much for your feedback and we will certainly ensure that we pass this along. Currently, RDNS is a service that our small business internet services do not support. Your SMB account is governed by limitations that only support specific services regarding Comcast-provided Static IP addresses. We do have the option of setting you up with our Enterprise or cloud solutions services which do have more advanced support options available. As always if you should have any further questions or concerns regarding your services or are interested in setting up services with either department we would be happy to assist.please do not hesitate to reach out to us through private message with your first and last name, business service address and account number or phone number.
