is it just me or...

I'm using Thunderbird to read mail and lately the only thing I've seen in the mail.from address is |North American Network Operators Group | and not the author's address which makes it really hard to tell who is talking to whom. I is just me, or has there been a list config change that is causing this? Mike

Correctly dealing with bots and scrapers.
by Andrew Latham 25 Mar '26

25 Mar '26

I just had an issue with a web-server where I had to block a /18 of a large scraper. I have some topics I could use some input on. 1. What tools or setups have people found most successful for dealing with bots/scrapers that do not respect robots.txt for example? 2. What tools for response rate limiting deal with bots/scrapers that cycle over a large variety of IPs with the exact same user agent? 3. Has anyone written or found a tool to concentrate IP addresses into networks for IPTABLES or NFT? (60% of IPs for network X in list so add network X and remove individual IP entries.) -- - Andrew "lathama" Latham -

New c-nsp, j-nsp, a-nsp, etc mailing lists
by Drew Weaver 20 Jan '26

20 Jan '26

I was a big fan of the *-nsp(a)puck.nether.net<mailto:*-nsp@puck.nether.net> mailing lists that now seem to be completely gone without any indication of whether or when they might return. I've been considering just setting up new ones. Please email me off-list if you think this might be useful. Thanks, -Drew

Hardware question
by Craig Smith 10 Nov '25

10 Nov '25

Hello, Is anyone out there aware of a fail safe switch/router/1U server where upon power failure or watchdog event 2 ports would fail to pass through data, but could also be assigned an IP address and act as a bridge in "normal" mode? The desire is to have an appliance that could perform monitoring and send telemetry in between a customer device and an Internet connection but not create a single point of failure or require multiple ISP handoffs. Best, Craig

CAIDA and Internet2 are working on a tool to assist network operators plan their RPKI-ROAs
by Steven Wallace 01 Nov '25

01 Nov '25

You can kick the tires here: https://rootbeer.testing.ns.internet2.edu/roa-planner/ The implementation remains fragile and will be unavailable intermittently, but we hope to improve it over the next couple of weeks. Please send me (ssw(a)internet2.edu) any suggestions, concerns, etc. From the help page: The RPKI-ROA Planner is a tool designed to help network operators efficiently plan their Route Origin Authorizations (ROAs), which are vital for securing BGP routing. To generate a comprehensive set of ROA recommendations for a user-supplied IP prefix, the Planner aggregates routing and registration information from four key sources: - Internet Routing Registry (IRR): Route Objects are gathered from services like https://stat.ripe.net/data/whois/. - Regional Internet Registries (RIRs): IP registration data is fetched from sources such as https://rdap.arin.net/registry/ip/. - Routing History: Historical routing data is analyzed using services like RIPEstat (https://stat.ripe.net/data/routing-history) - Global Route Views: The Planner includes routes observed in the global research and education community (via Routeviews). Crucially, these routes may be longer (more specific) than those typically seen in the Default-Free Zone (DFZ). Assumption: If a route was observed in the past, is currently visible, or is documented in an IRR object, it is a candidate for a new ROA. It excludes any candidate routes that are already covered by an existing, valid ROA, ensuring you only focus on what's missing. All candidate routes are presented to you in the table. You have full control to deselect individual routes or use age filters to exclude older, potentially stale data before the final ROA set is calculated. The Planner prioritizes generating multi-prefix ROAs (covering multiple routes with one authorization) over single-prefix ROAs. Using multi-prefix ROAs is the recommended best practice for maintaining cleaner, more efficient RPKI records. thanks! Steven Wallace Director - Routing Integrity Internet2 ssw(a)internet2.edu

You can read the blog post here: https://www.arin.net/blog/2025/10/29/nro-rpki-program-series-6/ We welcome feedback and discussion on the sidrops mailing list [2] and during the upcoming SIDROPS WG session at IETF 124 (Montreal, Nov 3) [3].
