What is xxxxx.geek local DNS suffix

We have been cleaning out a PC and found a DNS suffix when checking its IPconfig and found a XXX.geek.local as "Connection-specific DNS Suffix".  What is it "geek.local"?

is this computer a member of a local domain named "geek.local"? if not, does your local DNS server name itself this name? you may find the answer from your local router's settings.

the computer name has no ".local" within its name ... how do we know  our local DNS server name itself this name?

Do you mean with ipconfig/all?
bbaoIT ConsultantCommented:
you may first run IPCONFIG /ALL to learn your default DNS and gateway. it is quite common for a home and SOHO network they are the same IP.

if the router/DNS can be managed by accessing its web console, check it there. you need to have the admin account of the router.

That is where we got that name.  In the results of the ipconfig/all, the line "Connection-specific DNS Suffix" pertaining to the adapter say " XXX.geek.loca" where the XXX is a value of 4 digits.

Also the PC is windows 8 home edition
bbaoIT ConsultantCommented:
the DNS setting as well as the IP should be assigned by your local DHCP server, which is commonly also your local router and default gateway, and DNS sever. as I said above, check the settings there.

if it is home router, the setting is commonly at its WAN settings section or DHCP section.

Understood.  You are saying that "XXX.geek.local" DNS suffix was set by the router the pc is connected to, which is a tplink router.

What we want to know is what is "xxxxx.geek.local" DNS suffix that the ipconfig displays.

We have had cable modems and other types of routers (including other tplinks router) and usually the DNS Suffix name has some of it's router manufacturer name, like "vlan1.phub.net.cable.rogers.com" from a rogers modem, or "vlan.motorola.xxx" from a motorola modem, etc.

That said, why the DNS suffix says "geek" not something related tplink?  

Is "geek" from tplink router manufacturer?

hehe, the name was given by someone who configured the router. basically it is just a name. if you have to dig out the meaning behind the name, you have to ask that guy.

see below the screenshot showing how it works.
