.uk and .co.uk are both run by Nominet, the UK registry. Quirky stuff like .co.uk / .org.uk / .sch.uk 2nd level domains partly come around from .uk being the worlds first CCTLD outside the US (and as other parts of this thread say

BFD or Ethernet-OAM is the standard here. It can get a bit hardware dependant but getting <50ms failovers from software based BFD in BIRD or FRR is fairly easy, and I've tested down to < 1ms before with hardware based BFD echo. ~

This is due to advertising standards. They are required to advertise "average speed", although how this is actually calculated is nebulous. A&A not advertising can just say what the link speeds actually are on the product page

.uk being the TLD, and .gb being the ISO 3166-1 alpha-2 code is a quirk of history that comes with .uk being on the internet very early.

I once wrote something that did, as an internal tool. It was basically an MPLS traceroute tool that used LOC records on RFC1918 loopbacks to plot pretty maps (well, the lines were way too straight on long range links, but ...). It was used

I've always thought we could put a bit of general purpose TCAM into general purpose computers instead of just routers and switches, and see what people can do with it. I know (T)CAM's are used in CPU's, but I am nore thinking

Yes, but they run a bunch of other useful services for internet plumbers too. This would just be another "general good of the internet" service. RIPE for example run. Atlas: A cooperative service for internet reachability and meas

The idea of an IX, or IX peering LAN is simple in concept. It is a LAN (a flat, layer2 network), to which multiple ISP's can plug in routers. Like your home LAN might have 192.168.0.1 = router, 192.168.0.2 = laptop, 192.168.0.3 = phone

You should read https://datatracker.ietf.org/doc/html/rfc1627 for a path not travelled. Not everyone thought this was a good idea, and I still maintain the alternative path would have led to a better internet than

The general root servers generally don't support AXFR, but if you want to AXFR the root, you can do so from lax.xfr.dns.icann.org or iad.xfr.dns.icann.org.

There is work coming at the IETF to help with this. - Draft: DELEG (a new way of doing delegations, replacing the NS/DS records). - A draft to follow: Using the extensible mechanisms of DELEG to allow you to specify alternative transpo

We don't have leash laws like in the US, so it is common for dogs to just be allowed to run around in most community parks. The problem with sighthounds is they will lock on to squirrels, rabbits or other things, and running at 40mph w

I live in Scotland, have two former racing greyhounds, and I'm very grateful for a local farmer who has a dog run / playpark with an honesty box we can drop something in to help with upkeep when we give our two a nice run.

Yes. Layer4 TCP is pretty much just slapped on top of Layer3 IPv4 or IPv6 in exactly the same way for both of them. Outside of some little nitpicky things like details on how TCP MSS clamping works, it is basically the same.

True. But larger orgs don't buy "random laptops". The trick is to just buy laptops where you know everything works, and the company making them has a commitment to Linux. Buy your linux laptop fleet from Framework, System76,

If you ever need a quick hack to get v4 connectivity over a true v6 only setup, you can use a public DNS64+NAT64 Gateway. You can find a list at https://nat64.net/public-providers . So for most regular use, all you are doing

My memories of Ashton-Tate are weirdly the non-dbase products, mostly the ones the acquired. I specifically remember Multimate, the Word Processor, and Framework, the "office suite" I guess. But dbase was 90%+ of what Ashton-Tate
