Worsening google service reputation and abuse
by Jared Mauch 21 Aug '25

21 Aug '25

Is there anyone at Google that is able to address the ongoing abuse problems that are coming out of your services like classroom, groups and otherwise? Wanting me to create a google account for the addresses that are receiving the abuse does not scale and as the reputation continues to get worse, I don't want to block all google services - but getting someone to work with on the issues would be appreciated. X-Notifications: COURSE_INVITATION:792026619952-1755166651116 X-Google-Group-Id: 1087901814827 X-Google-Group-Id: 328755863 X-Google-Group-Id: 864553705765 X-Google-Group-Id: 295922276390 X-Google-Group-Id: 534760014314 Decade+ old mailman has the end-user accept invitations to lists, but google seems to not even use it's own tools so isn't really meeting what would be a general standard. I saw others complain about this as well, and i've had to configure various blocking of different google services which is a moving target of abuse. It's fair to say that a human should be able to send e-mail to an owner alias for a mailing list, but not subscribe that to a group or classroom. - jared -- Jared Mauch | pgp key available via finger from jared(a)puck.nether.net clue++; | http://puck.nether.net/~jared/ My statements are only mine.

Anyone on the list from Hulu?

Looks like Hulu dropped the record they had for one of our netblocks that has been working fine for years and now suddenly, it's causing issues for our customers. I sent an email into ipadmin(a)hulu.com on Sunday but haven't heard anything back. Anyone on the list that could help? Thank You, Mike -- Mike Lyon mike.lyon(a)gmail.com http://www.linkedin.com/in/mlyon

Breaking the Sorting Barrier for Directed Single-Source Shortest Paths

I was scrolling LinkedIn and came across a post that mentioned a research paper: Breaking the Sorting Barrier for Directed Single-Source Shortest Paths TLDR: Dijkstra got defeated after 40 years. It will be interesting to see what convergence times will look like with this implemented. Different formats of the same research paper: * https://arxiv.org/pdf/2504.17033 * https://dl.acm.org/doi/pdf/10.1145/3717823.3718179 Kind regards, Ryan Hamel

Recommended DNS server for a medium 20-30k users isp
by DurgaPrasad - DatasoftComnet 21 Aug '25

21 Aug '25

Hello all, Do you have any recommendations for recursive DNS servers for a medium sized (20-30k users) ISP. We have used powerdns and unbound but sometimes find the caching times a bit on upper side. Any suggestions between these two or anything new? Also need points on how much we tune the settings pros and cons if any. Thank you /DP

Re: : Can a prefix be never routed on Internet but used only for source address in IP packets?
by Jakob Heitz (jheitz) 20 Aug '25

20 Aug '25

ICMP packets from internal devices. Example “unreachable”. Kind Regards, Jakob ---------------------------- Question: Can a prefix be never routed on the Internet but used only one-way for source address in IP packets? That is. a user owns an IP prefix. They never advertise a route to it in BGP on the Internet. But they use the prefix solely for source address in IP traffic from a source to a destination (sink). In this set up, the destination server obviously cannot/doesn't return any acknowledgements etc. to the source. Anyone aware if there is any such known application in use on the Internet - even if it is rare? Thanks. Sriram
