NZNOG-People, I have just finished migrating all of the mailing lists held at The University of Waikato from one server to another. I don't have any reason to believe that anything's gone wrong, but please bear with me for today if it turns out that something has. - Donald Neal -- Donald Neal | Q: How many Aucklanders does it take to change Systems Programmer/Analyst | a light bulb?

Skinny Modems and RFC1918 DNS
by Simon Lyall 17 Jan '23

17 Jan '23

We are getting reports from a couple of people that some Skinny Modems are getting confused with some DNS records. It appears that if the IP returned from the lookup is a RFC 1918 one they won't return the result to the client. One modem in question has: Skinny Smart Modem VRV9517UWAC34-A-SP on it and I think VRV9517 is the model name. This appears to be a fairly recent problem, showing up since people came back from break. Not ruling out some other cause but direct testing of queries is doing the above. Possibly a recent software upgrade or "security" setting. Direct queries against the DNS servers themselves seem okay, it only breaks when you use the modem as the DNS server. Not confirmed for all of RFC1918 space, but definitly 192.168.1.x Anyone seen similar or know of a fix? (for now we are getting people to use 1.1.1.1 or similar for DNS). -- Simon Lyall | Very Busy | Web: http://www.simonlyall.com/ "To stay awake all night adds a day to your life" - Stilgar

Well, there are already unintended consequences from the particular messing with the DNS at the edge that we are talking about, including the migration of users to centralised DNS services away from local ones, in fact: even people who like the idea of DNS as a control plane should dislike this. > Of course, the real problem is the vulnerable devices, but taking the approach that all of those just need to be fixed is accepting a lot of harm in the meantime. They still need to be fixed, though. What measures like this do is relieve the need for fixes and make them stay broken for longer. > These are one-shot band-aids that don't solve problems; they just obscure them. I realise I've long past the point of becoming a grumpy old man, but that doesn't make this kind of thing a good idea :-) Joe

Hi, We at the National Library will soon begin our 2023 New Zealand domain crawl. As in previous years, the crawl is being run by Internet Archive, and some of you may soon see the crawlers as IA go through their initial setup with some test crawls. The user agent string their crawlers will be using is: NLNZ_IAHarvester2023 For more information on our domain crawls please see http://natlib.govt.nz/publishers-and-authors/web-harvesting/domain-harvest While we do our best to crawl respectfully, obey robots.txt, and break out of any crawler traps before grinding too much bandwidth, if you encounter any issues from us then please get in contact.
