So today the topic came up about how many website you can run on a single NIC card with out using host headers. My thought was “as many as you want!”. But it was implied that there was a limit as to the number of addresses that could be assigned to a single NIC. So, when I got home, I decided to test it out. Now, I have a little spoiler here that is revealed towards the end of the video. The conversation we were having at the time was related to NT4, and my test below was done on Windows 2003, IIS6.

But, that’s ok. It gave me something to focus in on for awhile and I had fun doing it. I was just getting ready to blow this box away since I had already used it for some other testing and the Eval license is like 7 days from requiring activation.

I got an email asking about the validity of certain hosts.
Namely whether or not 10.10.1.255 and 10.10.2.0 where valid IP addresses. When dealing with a Class C range, you won’t see hosts with the last octet of .0 or .255, because those are the network and broadcast addresses. However, when dealing with class B or class A addresses, these addresses become completely valid.

You only drop the 1st and last host of any network range. In the above example, the Network is 10.10.0.0 and the broadcast address is 10.10.255.255, so all IP addresses in between are completely valid to use. It feels very odd typing in an address of 10.10.2.0, but I assure you, it’s a valid address, as is 10.10.1.255.
Hope that clears things up.

Well, I think I got the basics worked out. My resume is now uploaded, and as you can see, there are download links provided in the most popular formats.

In addition, I provided a web version as well.  I think I spent the majority of my time today trying to get Microsoft Word to gracefully export from the .docx format to at least presentable HTML.   It’s certainly not as neat as I’d like it to look, but for the time being, it’s quick.  Sure, I could take about 20 to 30 minutes and clean up the HTML manually and make it look exactly like I want it to.  But I probably make at least 2 -3 changes to my resume each week.  Sometimes it’s just minor tweaks, but other times it’s adding a new certfication to my credentials.  And if I’m going to be making regular revisions, I need a quick and easy way to export my resume into several formats, including HTML.  So I guess that will be my 1st project!

In addition to providing recruiters and hiring managers an easy place to find my latest resume, I will also be using this website as a technical Blog.   I guess you could say that I’m one of those people that takes his work home with him.  I love to tinker in technology, and I have quite an impressive setup that I use at home to evaluate software, or simply train myself on new technologies.  My current pet project is setting up an iSCSI SAN using Openfiler.  I have a mid-sized dual core system with 6 hard drives currently setup.  The NIC is connected to an private router which then feeds into a private virtual port on my Hyper-V server.   The iSCSI targets are then being presented to multiple hosts to setup fail over scenario’s in Windows 2008.  I would like to evaluate the high availability of Exchange 2007, File Services, and SQL 2008.   After that I add the SQL cluster, I’ll add a seperate IIS NLB cluster sperated by an ISA 2006 server.

So if that didn’t bore you to death, you can subcribe to my RSS feed and check back for updates as I finish getting everything setup.
