    What is IP address 192.168.1.127

    I'm a network novice, so forgivvve this basic question.
    After reading Fred's latest write-up in the newsletter, I downloaded and ran "HouseCallforHome Networks" on my PC.
    It identified 192.168.1.127 as an "unknown device."

    Would someone please tell me how to find out what that address is for?

    Thanks,
    Dick
    PS,
    I even ran Karen's Discombobulator, and it came back with "no information."

    Dick,

    That is an address on your Home Network (192.168.1.xxx) are all addresses in your local node and are "non-routeable", i.e. "What Happens in Vegas Stays in Vegas" with 192.168.1 being Vegas!

    You can get into your router's software, in your case HTTP://192.168.1.0 or maybe .1 in your browser. Most router software will list your devices.

    From my Linksys EA4500:

    You can see the devices listed in the background and clicking on the i icon shows the info about that item including the IP address.

    Belarc Advisor will also provide a map of your network although not as extensive as your router.

    Note: the Linux system listed is the Router itself!

    FYI for some networks this would be what is known as a broadcast address. This would be rare but ...

    Just because you don't know where you are going doesn't mean any road will get you there.

    Here is some good information about IP addresses:
    http://www.bleepingcomputer.com/tuto...ses-explained/
    Note the section entitled "Private Addresses".

    The address you asked about, 192.168.1.127, is a "private" address. Private addresses are used internally on your network. They aren't visible to the outside world. However, there will be another IP address which is assigned to you by your internet service provider. This is the only address which is actually visible to the outside world.

    There are two reasons that we have private IP addresses:
    * There aren't enough IP addresses to go around, and so each one of your internet connected devices has a private IP address. The router has the only "actual" IP address, and you are using only one actual IP address, rather than 10 (or however many internet connected devices you have at home). The technical name for this is "NAT", and NAT allows you to have over 65,000 internet connected devices all sharing the one actual IP address! You will never need that many private IP addresses, but I'm sure you can see that a business might need several hundred at one location.
    * Since private IP addresses aren't visible to the outside world, your internet connected devices have some protection and privacy from hacking. It's not complete protection, but it is at least something.

    If you have a smartphone or tablet then Fing is an easy way to see what devices are connected to your network. Fing is available for both iOS and Android, is free and incredibly easy to use.

    Here's a screenshot of Fing on my iPad:

    One of the best things for your particular query - "Would someone please tell me how to find out what that address is for?" - is that it shows the manufacturer of each connected device (last but one column). Currently connected devices are shown in bold.

    I've had Fing installed since it was mentioned on Lifehacker a couple of years ago and have found it invaluable as a discovery tool.

    Hope this helps...

    Of course there is WakeMeOnLAN from Nir Sofer, which shows a table of IP addresses, Computer names, MAC addresses, Network Adapter company, User text (useful for comments and as a sort field), Status and Workgroup.

    For me, this is one of the most useful utilities I use (since I do a lot of Waking-on-LAN remotely).

    I think I would avoid Angry IP Scanner specifically because it uses JAVA!

    I forgot that one... and agree about avoiding Java.

    That's why I use good old V2.21.
