'ipconfig /displaydns' display over 200 DNS unrecognized, should we worry

We are having a problem with a connection and came upon recommended task where we were instructed to run the line "ipconfig /displaydns".   This displayed a series of sites unrecognized to us.

The result showed over 200 DNS and with the list actual sites and IPs.  The sites are in line "Record Name . . . . . :" and "CNAME Record  . . . . : ", the IPs are in line "A (Host) Record . . . :".

For example:
    in.greta.io
    ----------------------------------------
    Record Name . . . . . : in.greta.io
    Record Type . . . . . : 1
    Time To Live  . . . . : 41482
    Data Length . . . . . : 4
    Section . . . . . . . : Answer
    A (Host) Record . . . : 35.186.212.13

    Record Name . . . . . : p2-eiiarhhxducde-vnxdzw56kwg3gh6t-299593-i1.stbcast3-stb.metric.gstatic.com
    Record Type . . . . . : 1
    Time To Live  . . . . : 79151
    Data Length . . . . . : 4
    Section . . . . . . . : Answer
    A (Host) Record . . . : 216.239.32.62

So we wanted to know,
  • what is causing this?
  • should we worry?
  • what should we do?

I  got it, you mean check every site and google them one by one (yes, painstaking)
Kimputer

Some are not revealed by a simple google query, and needs quite a bit more research.

Ok, prior closing the question, can you suggest some of "bit more research"? (just a little to direct us the right way)
