Why did my CRAN routers change ?

Hey Comcast. What happened to my local & regional CRAN routers that I've had for years (hops 2 thru 9) ?

The IP addresses have changed and now some of them don't have rDNS data anymore. Can any employees please reply ?

Re: Why did my CRAN routers change ?

I want to know what the hostnames are and the geolocation stuff ! But that is just me. I also want to know the router type and the port and slot data. This stuff:

Re: Why did my CRAN routers change ?

Usually takes a bit for updated routes to show their rdns data. It should show up for you again in a few days. Either some new hardware was installed for you or a temp issue made your routing change while something is done.

Re: Why did my CRAN routers change ?

Hmmm.. It's already been a month. I had this same thing happen a while back on a couple of routers and it took a request to a Comcast insider that I know to get it taken care of. At that time the rDNS info was missing for at least a year..

Well you didn't say that in your post... haha. I can shoot a message up the chain to a guy to see what's up. Other than that, you are outside of my state so I can't check it at the local office or ask the HE tech.

Seems that the return path interfaces when looking at them from your end are different tshirt

Some of my forward ones are even different now.

well yeah, they would be :p
I was just curious so I picked a hop from your original trace as a target...those 2 failed to respond (only tried a few above and below, but the rest seemed ok) Just figured if his guys were cleaning up the "neighborhood" they should try and catch them all.

That's not necessarily always so but most of the time the return path is different than the forward.
