[NANOG] OAM and multiple choice questionsDavid Zimmerman via NANOG (Apr 18)
Hi, all. A few months ago, I got really good guidance here to pursue OAM instead of trying to use BFD in unnatural
ways. I've been reaching out to my vendors and through various searches, since the OAM space is wholly foreign to me,
and I'm currently on four different paths:
* IEEE 802.1ag<https://www.ieee802.org/1/pages/802.1ag.html> now part of IEEE 802.1Q-2022 CFM
* IEEE 802.3ah<...
[NANOG] Re: CGNAT growing painsJon Lewis via NANOG (Apr 17)
More like 10% here.
Juniper does support overflow, but IIRC, in a later release than we're
currently running, and the overflow requires a separate dedicated overflow
pool. We already had to move from a single pool to seven to solve the IP
Geo problem "one big pool" had caused. Configuring overflow pools without
breaking IP Geo [again] would mean doubling the number of pools (one
overflow pool for each regional pool). While...

I was just googling something related, hit this thread, and realized I'd
neglected to reply to some of the messages I should have responded to :)
The network is "fully" dual-stack. There are a couple of pockets of
legacy gear that didn't get dual-stacked when the rest of the network
was done years ago, and we're not subjecting those pockets to CGNAT. Our
policy has been, "if v4 is all you have, you keep your...

[NANOG] Re: ISPs in Spain are blocking CDN IP ranges to tackle soccer piracyTom Beecher via NANOG (Apr 16)
Strange, I do that on my home network and it works just fine.
It's not a CDN's responsibility :
A : To help a country enforce a law that was written without considering
the technical ways in which it could be enforced
B : To help if an improper technical solution is chosen that impacts other
services as well

Italy:
https://arstechnica.com/gadgets/2025/03/italian-court-orders-google-to-block-iptv-pirate-sites-at-dns-level/
Extract:
Just last year, Italian ISPs briefly blocked the entire Google Drive
domain because someone, somewhere used it to share copyrighted material.
This is often called DNS poisoning or spoofing in the context of online
attacks, and the outcome is the same if it's being done under legal
authority: a DNS record is altered...

You control the endpoints of the communication, so you may install
uBlock Origin in your browser.
Unless your browser happens to run on an iPhone, in which case - you had
free choice to buy a phone that supported ad-blocking or one where you
were prevented from ad-blocking, so you have nobody to blame for that
choice but yourself.
Unless you live in one of those weird social circles where the text
bubbles have to be blue or you get...

Why is it not also 100% that government's fault for wilfully and
intentionally making impossible blocking orders?
And why stop at ECH? Why not 100% blame Github's if China blocks Github,
for using TLS? You're running defense for totalitarianism here - not a
good look.
Yes, to help prevent totalitarian censorship, networks have been
designed to prevent anyone other than the endpoints of a communication
from learning what is...

Not for me, no.
30°C is where I will peak out for a charging event to 100% SoC, and then

[NANOG] Re: ISPs in Spain are blocking CDN IP ranges to tackle soccer piracyGary Sparkes via NANOG (Apr 14)
They're not the good guy in terms of being a centralized service, perhaps, but the technology they've introduced and
are pushing is technology I happily and enthusiastically deploy myself on my own services, though since I'm not going
through their CDN you can still easily block/restrict my services.
That, I think, is an important part to remember - the only fault cloudflare has here is being used by many services,
the...
[NANOG] Re: ISPs in Spain are blocking CDN IP ranges to tackle soccer piracyConstantine A. Murenin via NANOG (Apr 14)
Not quite, because the entire Wikipedia in all languages is then
simply blocked, so, they're not even able to read any of the other
articles from Wikipedia either, in any language. This violates primal
protocol design principles of flexibility and resilience, business
continuity and backwards compatibility.
Also, the same principle that prevents Spain from selectively blocking
a single Cloudflare site, also prevents me, as a network...

You cannot expect the entire world to have the same laws as the United States.
If laws of foreign countries specify that some content that's legal in
the US has to be blocked in said country, it's 100% Cloudflare's fault
for wilfully and intentionally making such blocking impossible apart
from blocking Cloudflare's entire network, affecting all the other
customers, too.
You can't have your cake and eat it, too. A...
