Seeking clueful Comcast contact re static IP address info
by John LeCoque 05 Nov '14

05 Nov '14

Hello all, Sorry to take such a basic issue all the way to NANOG, but my team has nearly 16 hours into this issue via phone / e-mail with no results. We just need the IP address information for our recently installed DOCSIS service at a location in Tallahassee, FL. Unfortunately we have had no luck with support (after many attempts), and our sales rep has made it very clear that he does not care. Is there anyone from Comcast here who could contact me off-list to help us get this resolved? I am very grateful for any assistance. Thank you, John

Re: Default routes on BGP routers with full feeds

Usually, when this is done, it is an adjunct to providing connectivity fast while the table is loading on a connection reset.

Back when I was in the ISP world I installed a default route pointing to a data capture machine. This let me detect which customers had port-scanning worms so I could identify them ahead of the abuse complaint (and ahead of the "why is my Internet so slow complaint). The scanners rip through unrouted space as often as they rip through routed space, so they were pretty easy to catch. Unfortunately, dealing with Grandma's virus laden machine was never easy.

I can tell you that I do not do that. Typically if my BGP connectivity to a carrier fails I would prefer we don't route anything their way until we get that resolved because it might indicate a circuit that is up but unable to pass traffic (very common with carrier Ethernet especially). It does not guarantee anything but the BGP session is at least showing me that the last mile connectivity is good. In our MPLS VPN network we use BGP passwords that provide a bit of protection in case the carrier dumps one of our circuits into the wrong VRF (it does happen) and loss of the BGP session helps ensure that I don't route traffic into a MPLS VPN that is not ours.

I often opt to leave one or more default routes configured with low priority (lower than BGP). The thinking is that if there is a fault with BGP, the router will still operate and the fault can be corrected remotely (in-band). The downside is that I might pass traffic for non-existing destinations an additional hop and put the load of generating an ICMP unreachable on someone else's router. --Blake Berry Mobley wrote on 11/4/2014 11:47 AM: > I'm wondering how many of you who are multihomed also add default > routes pointing to your providers from whom you are receiving full feeds. > > If so, why?

Is anyone using Tail-f software or know anything similar? We are looking for a solution that is vendor agnostic. Can do simple command like show interface so even non-network techs and CSR's can get basic is the port up or down type stats without having to directly login to the network.

BGP Security Research Question
by Anthony Weems 04 Nov '14

04 Nov '14

I'm a student in college learning about networking and, specifically, BGP. Does anyone have any statistics on the use of S-BGP or soBGP in the wild? I've read a few papers / RFCs on the subject (from Cisco and the like), but I haven't been able to find any information about actual usage. Additionally, do people scan BGP speakers in the same sense that researchers perform scans of the Internet (e.g. zmap)? -- Anthony Weems
