Didn't really think it was.  In fact 213.130.128.32 belongs to

NetServices Plc
Network Operations Centre
Waters Edge Business Park
Modwen Road
Salford M5 3EZ
United Kingdom

You see:  Salford.  You've got to worry, haven't you?!  ;-)

Mmm...  Thanks for your comments.  I discovered that the Netservices DNS 
(above) was entered as the DNS server IP address in the LAN section of 
my router settings.  But it isn't my ISP's DNS server (the addresses for 
which is in the main configuration screen for the router - and is the 
one I thought I was using).

I'm now at a loss to know what has happened here.  I wonder if  I 
changed the DNS IP address settings at some time (goodness knows why!) 
and forgot that I had.

But do you have any other thoughts? (If it's just the forgetfulness of 
old age, I don't mind;  but if it looks like nefarious activity, how can 
I check?)

I guess that NetworkManager will have picked up the DNS IP from the 
router, and written it to /etc/resolv.conf?

Thanks for your thoughts
