the ipv4 vs ipv6 growth debate
by Dave Taht 06 Dec '22

06 Dec '22

I use a web plugin tool called ipvfoo to track my actual ipv4 vis ipv6 usage. I wish it worked over time. With very few exceptions I am still regularly calling ipv4 addresses in most webpages. Has anyone done a more organized study of say, the top 1 million, and how many still require at least some ipv4 to exist, and those trends over time? -- This song goes out to all the folk that thought Stadia would work: https://www.linkedin.com/posts/dtaht_the-mushroom-song-activity-69813666656… Dave Täht CEO, TekLibre, LLC

ipv4/25s and above
by Dave Taht 05 Dec '22

05 Dec '22

I am kind of curious as to the distribution of connections to smaller companies and other entities that need more than one ipv4 address, but don't run BGP. So, for as an ISP or infrastructure provider, what is the typical percentage nowadays of /32s /31s /30s... /25s of stuff that gets run "elsewhere"? Is there any correlation between the number of IPs a customer gets and the amount of bandwidth they buy? Obviously "retail", home use is /32s and there's an increasing amount of CGNAT, but I can't help but imagine there are thousands of folk running /27s and /29s for every /24 or /22 out there. I've been paying 15/month for a /29 for forever, but barely use it. -- This song goes out to all the folk that thought Stadia would work: https://www.linkedin.com/posts/dtaht_the-mushroom-song-activity-69813666656… Dave Täht CEO, TekLibre, LLC

Power outages Maryland near Washington DC (Plane crash into power lines)
by Sean Donelan 03 Dec '22

A small plane crashed into high-voltage transmission power lines in Montgomery County, Maryland; near Washington DC. Most of the data centers are in Northern Virginia, but some are in Southern Maryland (Wheaton, Olney, Gaithersburg and as far away as Silver Spring). https://wtop.com/montgomery-county/2022/11/outages-in-montgomery-co-after-s…

Dear list, We have address ranges that are being blocked by sites like Ticketmaster. Customer support is able to assist, and unable to receive a response from legal or hostmaster emails. What are the recommendations for requesting a removal from the blocked list at these sites?

CfP - ICANN DNSSEC and Security Workshop for ICANN76 Community Forum in Cancún
by Jacques Latour 29 Nov '22

29 Nov '22

Call for Participation -- ICANN DNSSEC and Security Workshop for ICANN76 Community Forum In cooperation with the ICANN Security and Stability Advisory Committee (SSAC), we are planning a DNSSEC and Security Workshop for the ICANN76 Community Forum being held as a hybrid meeting from 11-16 March 2023 in the Eastern Time Zone (GMT -5). This workshop date will be determined once ICANN creates a block schedule for us to follow; then we will be able to request a day and time. The DNSSEC and Security Workshop has been a part of ICANN meetings for several years and has provided a forum for both experienced and new people to meet, present and discuss current and future DNSSEC deployments. For reference, the most recent sessions were held at the ICANN75 Annual General Meeting on Wednesday, 21 September 2022. The presentations and transcripts are available at https://75.schedule.icann.org/meetings/hvW7BbDtvbw4hoSTx, https://75.schedule.icann.org/meetings/WLtBZqEydncda7Dsr, and https://75.schedule.icann.org/meetings/8jcmXcKTEoPTr3NQw. The DNSSEC Workshop Program Committee is developing a program for the upcoming meeting. Proposals will be considered for the following topic areas and included if space permits. In addition, we welcome suggestions for additional topics either for inclusion in the ICANN75 workshop, or for consideration for future workshops. 1. Global DNSSEC Activities Panel For this panel, we are seeking participation from those who have been involved in DNSSEC deployment as well as from those who have not deployed DNSSEC but who have a keen interest in the challenges and benefits of deployment, including Root Key Signing Key (KSK) Rollover activities and plans. 2. DNSSEC Best Practice Now that DNSSEC has become an operational norm for many registries, registrars, and ISPs, what have we learned about how we manage DNSSEC? * Do you still submit/accept DS records with Digest Type 1? * What is the best practice around key roll-overs? * What about Algorithm roll-overs? * Do you use and support DNSKEY Algorithms 13-16? * How often do you review your disaster recovery procedures? * Is there operational familiarity within your customer support teams? * What operational statistics have been gathered about DNSSEC? * Are there experiences being documented in the form of best practices, or something similar, for transfer of signed zones? Activities and issues related to DNSSEC in the DNS Root Zone are also desired. 3. DNSSEC Deployment Challenges The program committee is seeking input from those that are interested in implementation of DNSSEC but have general or particular concerns with DNSSEC. In particular, we are seeking input from individuals that would be willing to participate in a panel that would discuss questions of the following nature: * Are there any policies directly or indirectly impeding your DNSSEC deployment? (RRR model, CDS/CDNSKEY automation) * What are your most significant concerns with DNSSEC, e.g., complexity, training, implementation, operation or something else? * What do you expect DNSSEC to do for you and what doesn't it do? * What do you see as the most important trade-offs with respect to doing or not doing DNSSEC? 4. Security Panel The program committee is looking for presentations on DNS, DNSSEC, routing and other topics that could impact the security and/or stability of the Internet. We are looking for presentations that cover implementation issues, challenges, opportunities and best practices for: * Emerging threats that could impact the security and/or stability of the Internet * DoH and DoT * RPKI (Resource Public Key Infrastructure) * BGP routing & secure implementations * MANRS ( Mutually Agreed Norms for Routing Security) * Browser security - DNS, DNSSEC, DoH * EMAIL & DNS related security - DMARC, DKIM, TLSA, etc... If you are interested in participating, please send a brief (1-3 sentence) description of your proposed presentation to dnssec-security-workshop(a)icann.org<mailto:dnssec-security-workshop@icann.org> by COB Friday, 20 January 2023. Thank you, Jacques On behalf of the DNSSEC Workshop Program Committee: Steve Crocker, Shinkuro Mark Elkins, DNS/ZACR Jacques Latour, .CA Russ Mundy, Parsons Ondrej Filip, CZ.NIC Yoshiro Yoneya, JPRS Fred Baker, ISC Dan York, Internet Society

Newbie Concern: (BGP) AS-Path Oscillation
by Pirawat WATANAPONGSE 28 Nov '22

28 Nov '22

Dear Guru(s), My apologies upfront if this question has already been asked. If that’s the case, please kindly point me to the solution|thread so that the mailing list bandwidth is not wasted. Situation: On one of our prefixes, we are detecting continuous “BGP AS-Path Changes” in the order of 1,000 announcements per hour---practically one every 3-4 seconds. Those paths oscillate between two of our immediate upstreams. Questions: 1. Is this number of events “normal” for a prefix? 2. Is there any way we, as the tail-end (Origin Announcer), can do to reduce it? Or should I just “let it be”? 3. [Extra] Is this kind of oscillation affecting user experience, say, throughput and/or latency? Thank you in advance for all the pointers and help. Best Regards, Pirawat.

MAP-T Implementation
by Will Duquette 28 Nov '22

28 Nov '22

Has anyone successfully deployed MAP-T? We are in the process of testing and have it working in our lab. We are running into an issue where the last half of the ipv4 prefix doesn't work. I.E. x.x.x.0/24 assigned x.x.x.0-127 works, x.x.x.128-255 does not. We are able to manipulate our DHCP config to allow for the handing out of IPv4 IP's. The CPE gets an IPV6 address and IPv6 only works, anything trying to be routed with an ipv4 address in the last half of the ipv4 prefix will not work. -Will
