DZ: Trump Media Org + Weird BGP Policy Stuff

You may be wondering how a personal network got such a low AS Number in the first place to then sell afterwards,

It turns out a few years ago one of the old Canadian (GONET) state/research networks gave back a whole bunch of ASNs they were not using, and ARIN allocated those very low ASNs to basically whoever applied first! AS954 being a former GONET ASN.

DZ: Trump Media Org + Weird BGP Policy Stuff

Interesting, it appears that AS954 (formally owned by a personal/hobby network operator) has (very likely) sold it to the Trump Media Organisation.

It's kind of interesting that they were interested in that in the first place, a low asn number has some sort of prestige in some circles despite it basically just being an integer, but it has no technical upside.

I assume AS954 will be hosting truth social eventually, I presume the thinking is that running stuff on your own AS will be more resilient against IaaS providers taking them down due to content policy.

(I've censored some of this screenshots primarily because I don't think anybody should be harassing any of the parties involved, so don't go and do that)

A screenshot comparing the whois output to AS954 from before the assumed sale to after, the current screenshot says the AS is owned by TMTG in Florida

In the end, it appears that Sparkle accepted the /3 from Airtel, and then Orange, Cogent, GTT and NTT also accepted it from Sparkle.

At least one of those carriers has now fixed their filters, that were faulty due to (in JunOS land)

route-filter prefix-length-range /7-/0

not being:

route-filter prefix-length-range /0-/7

Airtel fixed their stuff around 04:40 UTC today

Looks like AS9498 (Bharti Airtel) typo'd a /32, /31 or /30. And turned it into a /3 (aka, 12.5% of the IPv4 internet) and other carriers accepted it!

@phil_stevens they do actually serve some kind of purpose in the market, all be it marginal.

Because they act as instantaneous market makers they effectively allow you to buy and sell shares with low volume basically instantly, and some markets that's actually extremely useful.

The rest of their core business strategy is a little bit murky, but I take some pleasure in knowing that they are mostly just plundering other HFT firms

@cks Hah, the issue I was having was mostly with the "ISO from my browser" function of the newer MegaRAC.

The way they all work is that they start a websocket, and the websocket carries USB frames from your browser to the actual computer (aka a websocket gets plugged directly into one of your CPU's (AMD) or PCH's (Intel) USB pins)

This ofc does mean that MegaRAC's HTML5 thing contains a full USB Mass Storage device device implementation. If you didnt know this already, I apologise for the mental harm that it might have caused

@uvok RDNS "SLA"'s are on https://bgp.tools/features

Forward DNS is done every ~14 days or so.

Both data sources are resolved "in rack" on AS206924. There used to be a button to force a RDNS update, but it's a little messy and I'd just direct people to wait a few days for it to update instead.

v4 RDNS updates work by checking everyones DNS SOA's regularly, and if they have changed then it rescans, assuming it has not already done so for since last week.

@tj I'm not doing any high speed forwarding, I'm basically just looking for a modern 10/25G SFP NIC that has stable drivers. Most of my workload is TCP flows (aka, this is the future box that bgp.tools runs on). No VM's, so fancy SR-IOV is not needed etc

I plan to add ~50k PPS of UDP to it at some point, but that could easily be moved do another box with a X520 that I universally trust to not go wrong

Fielding Opinions on modern NICs: Intel E800 series or CX6 (or above?)

Not really a user of fancy features, I just need a NIC with drivers that don't want to kill me

I do not wish to see or be seen by Broadcom or Intel XL710
