Re: Connectivity status for Egypt
by JDuffy＠nww.com 28 Jan '11

28 Jan '11

I'm a reporter for Network World, and we're working on a series of stories re the Egyptian Internet blackout. I hope I can glean some information from the operators on this list for my story. It would be much appreciated. My question for NANOG operators is... Is the blackout disrupting your operations in Egypt, Northern Africa and/or the Middle East? Have you noticed any resumption of service since the outage went into effect on Thursday, Jan. 27? Also, a bill was introduced recently in Congress proposing an Internet "kill switch" to be used, apparently, in response to cyberattacks on the U.S.: http://edge.networkworld.com/news/2009/040209-obama-cybersecurity-bill.html… Do you have any opinions on whether this "kill switch" could indeed be employed here to thwart attacks... or to suppress communications during time of political unrest? As a network operator, would you support such a bill? And would you comply with it if it indeed became law? Thank you, and best regards, Jim Duffy Managing Editor Network World

Need provider suggestions - BGP transit over GRE tunnel
by Robert Johnson 28 Jan '11

28 Jan '11

My organization is planning to become multihomed in the near future. Currently we have redundant (router and physical path) links to a single AS where we get our transit, and speak BGP to them using a private ASN. This configuration has not been meeting our reliability requirements, so we will be getting our own ASN from ARIN, and moving from PA to PI IP space. Our new provider will be used for backup purposes only. We would like to minimize the monthly cost of this connection; to do this, we are planning to use a VZ business FIOS connection with symmetrical bandwidth to establish a GRE tunnel to a datacenter somewhere, and bring up a BGP session over that tunnel. I'd like to know if there are providers that offer such a service on a regular basis, and if so, if anyone is doing this and has words of wisdom. Thanks in advance.

Re: [arin-announce] ARIN Resource Certification Update

The scheme in Bill Manning's INET'98 paper might have worked for classFUL addresses, but not CIDR. I think there may have been similar problems with Lutz Donnerhacke and Wouter Wijngaards' scheme(s) from 2008. Joe Abley's problem statement on this list gets to one of the issues. Your answer to him of "New prefix-based RRs? And perhaps even a new .arpa or in-addr.arpa subdomain" is a bit short on details. I challenge you to work out the details. Once we have something concrete, then we can pick apart why it won't work, tweak, and repeat. -- Sam

.com DNSSEC operational message

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Over the next several weeks, Verisign will deploy DNSSEC in the .com zone.

PPPOE vs DHCP
by Paul Stewart 28 Jan '11

28 Jan '11

Hey folks... I'm meeting with a customer tomorrow (service provider, rural telco) and we're pitching they move to a PPPOE platform most likely. But to be fair, I'm looking to draw up a comparison so they are "well informed" of the pros/cons. Has anyone done this? I came up with the following brief start: PPPOE vs DHCP PPPOE Pros ---------- Allows full authentication of customers (requires username/password) Allows control over customer connections (suspend accounts, create accounts etc) Easily assign static IP to customer (no MAC address or CPE information required) Assign public subnet to customer with ease (no manual routing required) IPv4/IPv6 fully supported on Juniper platform as required Usage tracking (GB transfer) from radius generated data PPPOE Cons ---------- Requires PPPOE termination router (Juniper ERX for example) Requires Radius server(s) to assign and track customer IP assignments/usage Customers require username/password to connect Customers require PPPOE client software or router to connect 8 bytes MTU overhead DHCP Pros --------- Simplistic - plug and play 90% of the time No MTU overhead, full 1500 MTU frame size DHCP Cons --------- No authentication occurs (anyone physically connected can use Internet generally) No user tracking without tracking customer CPE MAC addresses No usage tracking builtin to DHCP (GB transfer) There are several factors involved here. The first major thing is that we believe the customer wants to move towards caps on their customer usage (X amount of GB per month). Today, they are doing static IP assignments but the interesting thing is that the CPE they have control over today (Comtrend routers with DSL modem builtin). I know there's not always a good vs bad here but looking for opinions from folks who may have already done this comparison for a "boardroom discussion".... Thanks ;) Paul

Found: Who is responsible for no more IP addresses
by Hank Nussbacher 28 Jan '11

28 Jan '11

"World to run out of IP addresses soon, Internet expert says" http://news.xinhuanet.com/english2010/sci/2011-01/26/c_13708282.htm "Vint Cerf, who helped create IPv4 in 1977 and one of the founding fathers of the Web, told Australia's Sydney Morning Herald that IP addresses will be used up soon, perhaps within weeks. "I thought it was an experiment and I thought that 4.3 billion IPv4 addresses would be enough to do an experiment," Cerf was quoted as saying, adding it is his "fault" that "we were running out of the addresses."" Glad we cleared that up! :-) -Hank
