comment WAF vs Firewall
Also - what you choose to deploy in your own environment when it comes down to choosing something like this more or less depends on the depth of your budget. WAFs provide more protection specifically for web applications but can generally cost the CapEx and OpEx proportinal to the specialization.

comment Can a large number of network hardware interrupts cause a machine to be underutilized?
It could also be an issue with speed/duplex configuration problems. Sometimes switches/NICs don't play well together when negotiating duplex. Especially if the switch or NICs are 100mbit, I'd make sure that it is negotiating 100/Full or 1000/Full if it is gigabit. (Working in a large datacenter, I've seen it happen often enough to make it worth checking.)

comment What is the name of the cable (RJ45 to RJ45) that can be used to connect from a KVM to Cisco serial port?
Thanks! I spend half my day sometimes reading cisco docs yet I didn't even think to link one. :)

Yes, crossover has a different pinout as well. It has a different crossing pattern rather than straight "rolling over" - (see pinouts.ru/NetworkCables/Ethernet100BaseT4Crossover.shtml) - so a crossover cable won't work in lieu of a rollover cable. Hope this helps!

comment How did Google acquire 8.8.8.8?
Here's an article on Network World that summarizes a few of the more highly-publicized routing hijacks: networkworld.com/news/2009/011509-bgp-attacks.html

I actually re-read the question. Wasn't completely answered.

There is, of course, a little more to this - for example, the smallest amount of IPs that can be allocated in a single block is a /24, or 256 addresses (254 usable). Above, google has two /24's allocated to them.

comment Randomly unable to connect to localhost web server
Even if you only have 100-300 (with a rare max of 500) connections showing in netstat (in a listening, time_wait, closing, etc. state) you could still be suffering from ephermeral port exhaustion because by default, Windows 2003 limits ephemeral ports to 1024-5000. These ephemeral ports will normally be recycled at a good rate so you won't hit the limit - but you might be hitting it on bursts. Check the registry for MaxUserPort under HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters - jump the number up (30,000 or more) and reboot to test. Hope it helps!
