I find that the state is invariably correct. Although the seems to be a lot of 'uncertainty' about how to spell "confusion".

private ip addresses from ISP
by adrian kok 17 May '06

17 May '06

Hi all Have you had this experience? Our router is running BGP and connecting to our upstream provider with /30 network. Our log reveals that there are private IP addresses reaching our router's interface that is facing our upstream ISP. How could this be possible? Should upstream ISP be blocking private IP address according to standard configuration? Could the packet be stripped and IP be converted somehow during the transition? It happens in many Tier-1 ISP though ! Thank you for your information

Right behind Comcast in no1 and RoadRunner in no2, but I'd never heard of them until they started showing up on my lists a while back...maybe a year or so ago. Anyone else seeing the same amount of problems with these guys? It's just interesting to me that whoever they are, as far as volume of problems from *my* perspective they're as bad as comcast and rr.... -- "Genius might be described as a supreme capacity for getting its possessors into trouble of all kinds." -- Samuel Butler

Reason: both are the location of big isp NOCs. Since you completely ignored the security aspect, I'll address your reference to Google Trends. This is what you are probably talking about: http://www.google.com/trends?q=porn If what you are saying is true, that's some pretty bad geo-location and YMMV, but what source are you using to discount Googles numbers? Are you saying that everyone on all 3 shifts in those "two large NOC's" are searching for Porn on Google? Or are you saying that all their netblocks are in whois and have roles that state their blocks are located at those NOC's? If it's the latter, that would support either you being innacurtae in your assumption about the Trend, or google being wrong. I'd need more proof that Google is that far off and that it would "appear" as though they are simply using whois registrations for geo locating in their Trends product. I'd tend to doubt it.

RE: About Cisco NM-2FE2W-v2

Correct, the NM-2FE2W-v2 is not supported by 2800 series routers. See http://www.cisco.com/en/US/products/hw/routers/ps259/products_data_sheet 09186a00801aa71c.html under Orderability, Availability, Compatability, Minimum Software, and Memory Requirements. -----Original Message----- From: owner-nanog(a)merit.edu [mailto:owner-nanog@merit.edu] On Behalf Of Andrew D Kirch Sent: Tuesday, May 16, 2006 8:40 AM To: nanog(a)merit.edu Subject: Re: About Cisco NM-2FE2W-v2 Md. kamal Hossain wrote: > Hi all > > I purchase a Cisco-2851 and NM-2FE2W-v2 module because i need 4 > Fastethernet interface but when i plug the module IOS don't detect the > module.Is there any specific IOS for the NM-2FE2W-v2 module?.now IOS > version is 12.3.If any one have any idea pls reply me. > > Wow, where to start on this one. I didn't realize this was Cisco's post-sales support line. Further, I don't think a Cisco 2851 exactly constitutes core network operations. In the future you would probably be better off with a cisco-related IRC channel, or web board. That being said, I'll see if I can't field this real quick. The 2851 is not powerful enough to route 1 port of 100bT Ethernet let alone 4. What feature set is your IOS revision? Without knowing that I doubt anyone could even begin to troubleshoot this issue. Have you checked to make sure the NM-2FE-2W is compatible with your router AT ALL? After reading the "Relevant Interfaces and Modules" documentation at cisco.com I do not see this module being used with 2800 series routers, or it's predecessor, 2600 series routers for that matter. This is of course all publicly available documentation. Everything I've seen points to them working only with 3600, 3700, and possibly 3800 series chassis. My best suggestion would be to pack up your router, and the network module and send them to a good home with a caring network admin to tend to them. If you would like, please contact me off-list as I've been known to provide shelter to abused and mistreated routing gear. > thanks > > Kamal > > -- > This message has been scanned for viruses and > dangerous content and is believed to be clean.

Whether a single user VPN session in which the user's laptop obtains an IP address from the VPN gateway, or a subnet extended out across a VPN to a remote office, the user(s) will appear to be at the location of the VPN concentrator. While ping latency, if even transported over the VPN, may show a greater distance than other IP addresses in teh neighborhood, there is no clear way to know why that latency is higher. It's odd this was omitted.
