Either @quad9dns 's 9.9.9.9 & 9.9.9.11 are down or my #ISP (#Vodafone #Germany) is fucking around with my traffic to hide their #downtime...

• Given that their own shitty speedtest doesn't load and @Speedtest / speedtest-cli is unable to connect to any testing servers, I'd assume they fuck with my #traffic.

I hope @BNetzA, @netblocks, @ooni et. al. take notes, cuz my patience runs thin...

In case anyone wounders: isup is just a ,bash_aliases entry to shorten ping -a -b -c 1 -D ...

@Speedtest @BNetzA @netblocks @ooni interestingly, now it reports back the correct, abeit still horrendous latency back after I complained in public.

not shure if @quad9dns had downtime or someone fucked around with my traffic tho...

Right after I got 10 gigabit internet at home, NTT Flets (the fiber network I'm on) announces the planned availability of 25 gigabit FTTH next year! They've also started considering offering 50 Gbit to homes…

It took 5 years for 10G to make it from Tokyo down to Kagoshima, so I guess I have another 5 year wait for 25G?

They also provided this lovely diagram

Anyone know how to change the MAC address properly on OPNsense?

I've tried putting `ifconfig igc1 ether AE:CE:55:0F:F1:CE` in `/etc/start_if.igc1` but it doesn't seem to take.

Yes, I need to actually do the MAC address and not use the proper spoof function since I'm trying to ensure a well-known link-local v6 address (ask me about mDNS at your peril)

Comparing devices at the office this afternoon.

A small office desk with two MikroTik networking devices being compared. A white MikroTik Chateau 5G router with two external antennas sits at the back, while a smaller dark gray MikroTik hAP ax lite LTE6 stands in front of it, connected by a cable. Both devices use two different sims of the same mobile provider. In the background, a gray stand with a FreeBSD sticker is visible next to a wall radiator.

Wasting bunch of time reducing the public IPv4 usage on AWS for a client to reduce recurring monthly costs (AWS charges by the hour for IPv4s)

There are things AWS doesn’t even support that would help, like giving an RDS instance a public IPv6 without public IPv4. It's dual-stack or die! Please, I don't need any IPv4…

I pray for the day all networking is #IPv6 native and any IPv4 is just gateways for backcompat for laggards…
