TechExams.net IP Subnet Calculator for Windows - v1.0

I'm pleased to announce our version 1 of our IP Subnet Calculator for Windows is now available.

If you have a beta version installed, you will need to uninstall it manually because this is not an 'upgrade' but a rewrite and has a different name.

www.techexams.net/ip-subnet-calculator

Version 1.0 features:

- Calculate prefix, mask, subnets and hosts based on IP address and any of the former
- Display class, network, broadcast, first host and last host for current IP address
- Calculate list with network and broadcast addresses and valid host ranges for all subnets
- Save list of all subnets to TAB delimited text file
- Print list of all subnets in network
- Recognizes Private addresses
- Recognizes APIPA addresses
- Recognizes Loopback addresses
- Recognizes Supernets
- Always on top 'pushpin'
- Show binary results

v1.0 also recognizes invalid all zero network address and all ones broadcast address combinations

System Requirements:
Any Windows machine running the .NET 2.0 Framework. If you don't have that installed yet, you can have it install automatically when you install our subnet calculator, if you are online.

Agreed this is an excellent addition to the site, and let me say job well done!

Webmaster

Thanks guys, I'm glad you like it!

If only we can get Cisco to get real and put this in their test engine!

Sweet! I'll add it to my collection..............

As mentioned in my PM to you, very nice. Thank you!

Awesome. I can't wait to try it out as soon as I flip on my Windows box. I've tried several online subnet calculators, but only a few have been available offline.

Thanks for the relentless effects you're putting in here Johan.

We're on your side.

Much appreciated.

Webmaster

Thanks for the comments all, it was a lot of fun to create, but I'm really glad your finding it useful.

Something I didn't mention yet earlier:

Once the network, broadcast, first host, and last host for the current IP address is determined, click on the label "Network address:". That will open an 'ugly' dialog box showing the ip address and mask in binary, and how the network address in binary is determined by 'anding' the ip addy and the mask. I.e. notice that when a bit is set to ‘1’ in both the mask and the IP address, it will be set to ‘1’ in the network address as well.

In a future version this will be a nice clean window showing the broadcast, first host, and last host in binary as well, and 'depict' how these are determined.

Very Nice Nice Nice Nice Nice Nice nice. Say there is an echo in here. Now we don't need that ugly yellow in the Boson one. Well done Johan.

Hi Just added some news on my website about the new program however one user had a very good comment.

Could you possibly tell me why name a download file after the name of a well know Trojan. I mean really SubZero_1_0_0_38.zip?

I'm sure there are many people who would be wiery of downloading a file named like that. On second thought, it could be developer humor.

eurotrash

It's the project code name.

sprkymrk

Hey, that just leaves more download bandwidth for the rest of us.

Actually, there is a trojan name for just about everything nowadays.
Even a trojan named "viagra".

http://www.simovits.com/trojans/trojans_name.html

Webmaster

Indeed, it's merely the project name of this beta. Obviously named after a character in Mortal Kombat, not after a Trojan nor the IP Subnet Zero.

The project name won't be in the final version.

Any particular reason for posting this here instead of replying to my email in which I already asked you to wait for the final version...?

Thanks for the plug on your site though!

linksysinfo

The post on our own forums is public, so i posted it here as a question rather than an email. I meant no negative publicity by the posting though, i just thought it was quite a curious name.

now I know.

Webmaster

Hey, I was just kidding. No problem at all. You are right, it 'is' a 'curious' and flat-out bad choice for an app name, but it's not the name of the app, just the 'temporary' name of the project. Omni pointed this out with an earlier beta so I was aware of it, and it's one of the minor issue I mentioned should be resolved before you add it to your site. But you certainly won't here me complain about your enthusiasm to plug it while still in beta. So thanks again!

Webmaster

Just to add, for others as well: we expect to release version 1.0 next week.

I guess my eyes weren't fully open yet... I forgot to update the bottom link on the download page

it should be

www.techexams.net/ip-subnet-calculator/SubZero_0_7_0_0.zip as in v0.7.

chiefcrazythumb

When I extracted these files they came up as "subzero application" and not subnet calculator. Whats the deal?

chiefcrazythumb

Opps... Ok, I just read your posts... yep bad choice for name... I will install it now

Very nice - thank you!

As a fellow software developer,I`d like to just say Good Job!

Unfortunately I don`t run Windows so I cannot test this myself, but it looks pretty decent for those who need it!

Webmaster

@mobri09: thanks, nice to see you're still around btw.

@networkengineer: All I can say based on that output is that it probably has to do with .NET and not the subnet calc in particular. You probably should wait for the final version, but you could try to reinstall (or update if necessary) the .NET framework. It could also be my shameful bad choice for the app file. Also, are you installing it on XP or Vista?

@Tesl: Thanks, I appreciate that. Normally I'd say I'm not a software developer, but I've been working on two other apps for the past 10 months so... I need to take a Cisco test again soon just to make sure I haven't changed into a coder indefinitely...

This was my first VB.NET app, and although I can complete it to work properly, the code is kinda 'funny' and by now I can do much better. I've actually already started on a complete rewrite, same interface though (and different app name

). The main thing I want to work on a bit before releasing 1.0 is the speed. I'll post again later this week with an update or v1.0.

Webmaster

OK, I uploaded version 1.0.

www.techexams.net/ip-subnet-calculator/

In addition to fixing bugs reported by beta users, mainly related to input validation, version 1 recognizes invalid all zero network address and all ones broadcast address combinations - they will appear in red, for example:

v1 also has improved recognition and support for supernets and a cleaner binary result window:

If you have a beta version installed, you will need to uninstall it manually because this is not an 'upgrade' but a rewrite and has a different name.

Although it is no longer in beta, if you have any comments or suggestions or find any bug please let me know. I'm going to release version 1.1 or so in a couple of months when I get that codesigning certificate (so Vista doesn't complain).

thanks for your effort, your friend utpia
