Comcast CRAN

From what I remember, you could tell if you were on CRAN if most of the hops in a tracert were Comcast. Im in DE and I don't seem to be on it.

Tracing route to www.dslreports.com [209.123.109.175]

over a maximum of 30 hops:

That's CRAN. Some people get more hops, but that's what those hops of yours are.

What would it be without? I thought CRAN kept you within Comcast's network as much as possible?

5 out of 13 aint bad.
At some point it has to leave Comcast and go where ever it's going.

Nearly as I can tell, the object of CRAN is to keep you on the Comcast network from your location to the nearest peering point to the destination. E.g., on Comcast from Seattle to, say, Dallas-Ft. Worth before hitting the peer backbones for those Richardson, TX game servers.

How the packets are routed past the peering point is out of Comcast's control.

In DE, we only have a couple CRAN hops depending on where you're at in the state. As you can see on mine, #2 is my headend, then #3 - #8 are the CRAN hops - leaving the Comcast network out of Philly.

But based on a tracert to that last Comcast IP on YOUR list, it looks like you are in Southern DE - and are on the Baltimore/DC network instead of the PA/DE/NJ one that i'm on. Notice hops #8 & 9 where it goes on the "cbone" - which is how the regional CRAN's are connected.

Is there a reason why some peoples cran hops have hostnames and others are just IP addresses?

For example, when I trace google it looks like this:

C:\>tracert google.com

The cran hops don't have any hostnames. But previous in the thread, others could see names that would give an idea of location. The OP has this too where the hops are un named.

Yes, because Comcast hasn't assigned any forward or reverse DNS to them. It's their own responsibility. The reason (plain, simple, and factual): their hostmaster is lazy.

Comcast is great in the DC/Baltimore area. Ive had it for 2 yrs, not 1 TV/CHSI outtage so far. Someone is always home, No reports of ANYTHING not working during that time. Always someone home using TV/CHSI.

If you see the 68.87 address in the first few hops of your traceroute, you're on the CRAN. 68.87 is the comcast network prefixes/subnets. The amount of those hops you have is dependant on how many it has to go through to get to the closest peering point to where you want to go.

Maybe it is just that no hostname is needed, you know it is within the Comcast network so why add a hostname?

Because they've done it elsewhere? For standardization? To make people like me quit whining? I can come up with a ton of good reasons to make it the same across their entire network.
