Sure - I could. But that's extra devices and usually extra power points at those locations (esp if you want any POE - I doubt there will ever be a switch that can be powered by, AND deliver POE at the same time). So it's extra devices to buy and support and manage which is why I decided against it. Having the extra ports doesn't stop me doing it in the future either.
The flip side of course is that a failure in one of the big switches takes a LOT of things offline and it's more expensive to replace. Not the VM cluster or servers - but about half the other devices (e.g. one of the WAPs, half the desktop points etc).
OK Telstra has to record the source and destination numbers of all the calls - right? Here's a sample record (not that drawing a table is easy so work with CSV here):
FromID, ToID, TimeStart, TimeEnd
0299999999, 0288888888, 20090617135834, 20090617140711
How would you like to determine whether the number 0299999999, which is not owned or operated by Telstra today, and which was not owned or operated by Telstra in 2009 either, was or was not an unlisted number at the time of the call? Because its state right now is completely irrelevant - the state at the time of the call is the important and relevant piece of data, and it doesn't exist. And the reason it doesn't exist is that this is a record designed for billing and cross-checking, not for customer view (if you're arguing against unlisted numbers in toto, you've never been stalked).
Sure they do - all the major web servers and hosting platforms can use and define vhosts (it's just that the mechanism for creating them differs on each platform). IIS for example, if you create a new site, using "All IP Addresses" port 80, will require that you designate a host header so that the HTTP engine can route the request to the right Web Site (and corresponding content). All IP Addresses port 80 with an empty Host Header acts as a "catch-all" and is assigned to the Default Web Site. Which you generally disable, and create your own config for, if you know what you're doing. Apache, on the other hand, configures those vhosts in text files (nowadays under sites-enabled, as I recall). But the functionality is all there on pretty much all major platforms.
Now if you're arguing that the administrators of IIS servers are exponentially less likely to have a clue about host headers, when compared to their Apache/nginx counterparts - well then from my experience you're absolutely right (my history is MS consulting, and the number of IIS admins who want 20 IP addresses for 20 sites because they don't get how to do host headers, DNS resolution etc, cannot be counted - the reverse can be counted on both hands over 20 years of doing this stuff).
No, it means anecdotal evidence is to be taken as better than no evidence whatsoever. Not everything is black and white, one side of the fence or t'other.
Consider this as a scale - Peer reviewed, multiple-source reproducible trumps anecdotal evidence, but anecdotal evidence is still better than the absence of any evidence on either side.
Cop 1: "He looked like he was hiding something, yer onner". When we stopped him he kept looking around and acting strangely."
Cop 2: "Yeah, yeah, wot he said."
You: "I did no such thing, your honour."
Judge: Both cops say you did, 2 trusted public officials with no reason to lie against 1 obvious reprobate, probable cause, case dismissed with prejudice.
Except the fuckers crashed my machine when they pushed out the update.
Citation needed, since I recall no such major outcry. Your machine is probably one of the ones with 25 browser toolbars, or ten download accelerators, or fifty outdated browser plugins, or a couple of undetected rookits etc., which is usually the reason behind a security patch "crashing your machine".
And if Windows closed the app with unsaved work, you'd be here whinging that Microsoft destroyed your work. And if you really gave a crap, you'd go in and change the Windows Update setting from "Automatically install" to "Ask me first".
Microsoft has done some seriously stupid stuff. And some bad stuff. But if you want to abuse them, at least abuse them for the stupid stuff not the sane stuff.
