what is a new 192.168.0.150/17 network mean?

Look at screen shot.
i rebooted and it said new network detected!
I chose a public place until we get to the bottom of the this
never heard of a /17 you??
I know my static local ipv4 address is 192.168.0.150 but why after a reboot does cis 6 say new network found 192.168.0.150/17???
how can you find a new network off of a static address???

see attached…

A 17 bit mask simply means a subnet of 255.255.128.0. This is not usually the number of bits used in a class ‘C’ address, but with a reserved address such as 192.168.0.0/16 you can do pretty much what you like.

Can you run an ipconfig /all and post the results.

Here it is

look at my IPv6 it feels like someone just activated it or something. my provider is ipv4.
and i have not done torrents in hours…i just don’t feel right about this one…
I have not had utorrent open either. when it said new network i chose public until we figure out what is going
on i will not login into the forums out side of the virtual kiosk either that’s for sure…I use www.opendns.com for my name servers (DNS) and their client. I see a 17 in my IPv6 address. is that the windows default failed dhcp ipv6 address??before the reboot i was using cyberghost vpn for a while but it has given me a hint of trouble or anything. i have never seen new networks ever not even once like this on this pc. for that matter Never seen anything like it on a static address you?

What’s the IP block for the TAP adapter? As far as IPv6 is concerned, what you have is normal for Windows 7/8. You can disable the tunnelling adapters by using:

netsh int teredo set state disabled
netsh int ipv6 isatap set state=disabled

It looks like you have a router, can you check the DHCP settings? Any wireless around?

i have wireless around. it is set to only allow access to the 4 mac addresses it is told. No one is connecting. i can check the client list in the router and see if my allow only 4 mac addresses is allowed is working. i regularly watch the wireless. what would you like to know about the router’s dhcp settings?
it’s a ubee router on roadrunner lightning.it does Ethernet, wireless and telephone all in one device.
it’s the most stable fast router i have ever seen except the wireless n drops constantly so it is set to wireless g only.
i can login and have changed the default admin settings and set the 4 mac addresses allowed on the wireless and the encryption key.
the TAP adapter is dhcp see attached screenshot

On most routers you can configure the IP address/mask allocation for DHCP - the address range used and the mask applied. As CIS should only detect a new network if it’s connected, wired or wireless, I’m trying to ascertain where this new mask came from.

From what I can see the adapter on the PC is wired, do you have a wireless option too, maybe a USB/dongle, If so, you may have detected a neighbours network.

That disabled wireless adapter was integrated into the motherboard but i removed some wires and things from it and half destroyed it when i was upgrading my video card.
this is an hp pavillion pc Intel quad core 2.5 ghz. I replaced the power supply and put a 600w corsair in it. another wd black 7200rpm hard drive and added a nvidia gtx460…i suppose the wireless adapter could have blinked a moment of life but i doubt it being in it’s shape and disabled…you would not believe how stuffed this little tower is. i have another identically stuffed hp pavillion pc but it’s an amd 3.3 ghz…both running windows 8 pro and cis 6.

i have found in the event viewer someone started the wlan auto config service and ipv6 dhcp service was started. how the hell do i stop the ipv6 dhcp service…

WLAN Autoconfig shouldn’t really be doing anything unless it see a wireless adapter. If You can disable the service from services.msc.

As far as DHCPv6, you don’t appear to have native IPv6 (from your ISP, so it’s not really doing anything. If you simply don’t want to see this uncheck IPv6 on the network adepter. You could also disable router discovery for IPv6, but it may be best not to, at least for now.

I disabled the auto wlcan config.
here’s a screenshot of my router dhcp. nothing going on here

At this point, it’s going to virtually impossible to identify why CIS picked up this new network. All you can do is keep an eye on things. Check you router logs and CIS logs and report if anything untoward happens again.

The only other suggestion, download one of the free ‘wifi checking utilities’ and see if it can find any networks using the address range used in the alert…

Edit: This may be something or nothing, but I noticed this post, where the network discovered also has a 17 bit mask, which is incorrect for the address type. I’m now wondering if there’s some inherent problem with network discovery/reporting in CIS, as the IP address in your situation, is actually the same as that already allocated, it’s only the mask that changed. Probably warrants more investigation.
