Others such as Eli Lily or the UK Gov Dept of Pensions really don't need so many addresses

Someone in the UK government pointed that out recently - it turns out that "Dept of Pensions" allocation is actually used across most of the government as some sort of VPN extranet with various external contractors. Apparently, since they all use different RFC1918 blocks internally, they can't all be VPNed into any single RFC1918 block: they needed a globally-unique block for that purpose.

British Telecom uses the 30.0.0.0/8 block for managing all their customer modems - that block is actually allocated to the US DoD, but they don't allow external access to it anyway, so there's nothing to stop you using that block internally yourself as long as you don't need to communicate with any other networks using the same trick. Better than wasting an entire /8 of global address space just for internal administrative systems - or a /9, like Comcast grabbed back in 2010.

My inner geek - who cares about efficiency - would love to see all the legacy blocks revoked. I'm sure the DoD could use 10/8 instead of 30/8 quite easily for their non-routed block; the universities could easily fit in a /16 instead of a /8, or smaller with a bit of NAT. Still, we should be moving to IPv6 instead now: give each university and ISP a /48, or /32 for big complex networks needing multiple layers. I just have a nasty feeling we're in for a long time of CGNAT spreading instead - where we currently have ISPs that don't offer static IP addresses, in a few years they'll be refusing to issue anything other than a NATted 100.64/16 address.

Journal: Reminiscence XP 6

Journal by jawtheshark
As I said in my previous journal entry, I'd install Windows XP Home (OEM) in a Virtual Machine today in order to commemorate the death of XP. I documented it with screenshots. Yes, I know, it's Facebook album, but it's public. It was the quickest way to get something online.
From VM creation and installation from SP3 OEM ISO to fully patched in 1 hour and 30 minutes. Not a

Yup, you don't understand mature software. That's ok, most people in tech don't. As for the media? Slipstream the latest SP into your ISO and you're done. I have installed XP previously in a Xen DomU and itt' drop dead easy. 7 is a "just ok" replacement and only by virtue of Vista being so bad.

To understand a program you must become both the machine and the program.
