Why does MPro7 have to be so expensive?

grumble, grumble, grumble...

Broadcast address: 192.168.255.255
Amount of addresses: 2^16 = 65 536
Next network: 192.169.0.0/16

I thought the broadcast address as such: all the bits in the variable portion of the address resolve to 1 (which is the same thing, of course. I just never thought it to be the last address, for some reason). But now I know I'm finding broadcast correctly.

I do remember something about 2^x.... Now I know!

Additionally your subnet mask is 255.255.0.0, and I'd guess your gateway is 192.168.0.1. (Note that the gateway and broadcast address are not standardized and can be different, but a gateway is rarely different from the base address + 1 and the broadcast is even more unlikely to differ from its default of last address.) Subnet masks are nothing more than bitmasks, and have a 1 for a bit that's 'static' within the subnet (always the same for every address) and a 0 for every 'variable' bit. Since the last two octets are variable in /16s, the first two are static. This converts to 255.255.0.0.

I thought the base address +1 would give the first usable host? Is the first usable host, therefore, gateway +1? Anywho, you have confirmed my findings of subnet masks

Subnets that use entire octets are easy to work with (/8, /16 and /24); most confusing elements kick in at in-between range sizes. A nice example is the student-range of my Uni's address space. My own PC for example is 130.89.161.14, and I happen to know the network is a /20. With 32-20=12 variable bits there's 1.5 octet we can designate as 'variable'. A bit of binary maths and you end up with these details:

Base address: 130.89.160.0
Broadcast address: 130.89.175.255
Amount of addresses: 2^12 = 4096
Next Network: 130.89.176.0/20
Subnet mask: 255.255.240.0
Gateway: 130.89.160.1

I just remember that the the prefix for the last octet is /24. If something like /26 or /22 pops up (which is usually the case), I just add or subtract the corresponding bits. All this 1.5 of an octet is confusing <_>. Again, it's just another way of looking at it.

Next network: increment the last non-variable bit of the network prefix, and use the same amount of bits.

I think this is my only real problem. What if, hypothetically, the network looked something like this:

192.89.224.0/19

what would the next network be? There isn't a last static bit to increment with that prefix and that address. As for the last usable host, it's broadcast address -1, I hope.
I appreciate the help.

Yay! The company that I've been on long term assignment to offered me a permanent job. Same work, but big raise and full benefits. This makes me happy.

Well Jelco, I took the damned test and scored a 67. My average came out to a solid 82 for the 9 week grading period. S'alright, if you ask me.

I'm happy for you, keep up the good work!

Thank you!

How nice of you to leave my nercomancy topic! But now it doesn't make no sense anymore, so you might as well remove it..

How about new poster moderation? That should stop most of the spammers before anyone sees them.

But I like spammers, they bring live to these forums!

With November upon us, the most wonderful time of the year is quickly approaching... when I decide which gun to buy with my tax return.

The next several months will be filled with research, questions, pondering, and debate. Long guns or pistols, calibers and capacities, bells vs. whistles, so much to consider! Let the season commence!

I saw this gun on mythbusters, is was a revolver for hunting purposes and that gun was just a sheer hand-cannon, it blew someones thumb of because gasses escaped from the chamber and he was apperently holding the gun the wrong way. Otherwise good gun though, good stopping power I imagine might someone come into your home

Nobody cares about your peni---gun.

That's what makes it random.

And don't project your inferiority complex on me. I'm comfortable with how I am, I encourage you to be as well.

Good fucking god, just how much shit does a brand new laptop bring installed?

Seriously, I got a laptop last week for my mother, and I was looking into it now to essentially finish properly setting it up. At launch, with essentially factory settings, the bloody thing has over 90 processes running (by comparison, my heavy use desktop tends to have between 30-70 depending on how much shit it has installed). I can identify at least 7 tray icons with no business being there, and I suspect, with no hyperbole, that a full two thirds of everything currently installed is manufacturer specific software with dubious utility at best.

Honestly, I really should format this back to a truly clean slate, but don't actually feel like thralling the internet for all the drivers :/
