Spectrum residential IPv6 rDNS - thank you !
by Brandon Applegate 10 Oct '18

10 Oct '18

Wanted to give a shoutout / thank you to Spectrum for this. Just noticed today my home PD now has dynamic/synthesized rDNS for IPv6. Some of my dumb little scripts outputs are a bit happier today ! :) -- Brandon Applegate - CCIE 10273 PGP Key fingerprint: 0641 D285 A36F 533A 73E5 2541 4920 533C C616 703A "For thousands of years men dreamed of pacts with demons.

DHS: Report on Alerting Tactics
by Sean Donelan 10 Oct '18

10 Oct '18

Communication service providers play a critical role, but too often view public alerting as "someone else's job." https://www.dhs.gov/sites/default/files/publications/1051_IAS_Report-on-Ale… Report on Alerting Tactics August 7, 2018 However, there was not consensus on which combination of tools is generally most effective. The alerting ecosystem consists of multiple systems alert originators can use to reach the public with alert and warning information, “as well as diverse channels of message delivery, distributed sensing devices, and feedback mechanisms.” Alerting ecosystem components include: • Alerts and warnings from Federal, state, and local alerting authorities to the public; • Coordination between alerting authorities and other governmental entities (e.g., 911); • Public information sharing to alerting authorities (e.g., social media requests); and • Public information exchange between community members

Spoofer Report for NANOG for Sep 2018

In response to feedback from operational security communities, CAIDA's source address validation measurement project (https://spoofer.caida.org) is automatically generating monthly reports of ASes originating prefixes in BGP for systems from which we received packets with a spoofed source address. We are publishing these reports to network and security operations lists in order to ensure this information reaches operational contacts in these ASes.

Buying IPv4 blocks
by Ross Tajvar 08 Oct '18

08 Oct '18

Hi all, My US-based employer will be starting a new business unit soon that will require IPv4 addresses (aiming for a /22 to start with). I know ARIN has a waitlist (though I'm not sure where they're getting new IPs from), but the faster way is to buy blocks from people who already have them. I'm aware of Hilco Streambank - are there any other auctions? If I want to buy via private sale, does anyone know of ways to find sellers? Thanks, Ross

Not announcing (to the greater internet) loopbacks/PTP/infra - how ?
by Brandon Applegate 05 Oct '18

05 Oct '18

Hello, I’ve seen mention on this list and other places about keeping one’s PTPs / loopbacks out of routing tables for security reasons. Totally get this and am on board with it. What I don’t get - is how. I’m going to list some of my ideas below and the pros/cons/problems (that I can think of at least) for them. - RFC 1918 for loopbacks and PTP - Immediately “protects” from the internet at large, as they aren’t routable. - Traceroutes are miserable. - Use public block that is allocated to you (i.e. PI) - but not announced. - So would this be a totally separate (from user/customer prefixes) announcement and allocation ? In other words, let’s say you were a small ISP getting started. You manage to get a /20 from a broker (IPv6 should be “easy”). Do you also now go out and get a /23 (I’m making these sizes up, obviously all of these will vary based on ISP size, growth plan, etc.). You have the /23 registered to you (with proper rDNS delegation, WHOIS, etc.). But you simply don’t announce it ? I’d say I need this /23 day one to even build my network before it’s ready for customers. - On the IPv6 front - would a RIR give you your /32 and then also a /48 (for loop/PTP) ? - Deaggregate and not announce your infra - Bad net behavior out of the gate with this method. The opposite of elegant. - Keeping with previously made up / arbitrary prefixes - for your /20 - you’d end up announcing 2 x /23, 1 x /22 and 1 x /21. I’m too lazy to enumerate the IPv6 gymnastics, but with IPv6 you could “waste” a bit more to get to boundaries that are a bit easier to work with I suppose. Thanks in advance for insights on this. -- Brandon Applegate - CCIE 10273 PGP Key fingerprint: 0641 D285 A36F 533A 73E5 2541 4920 533C C616 703A "For thousands of years men dreamed of pacts with demons.
