Thanks for your response.

I have an entry in /etc/dhcpd.conf on my desktop

        host carrie-ether {
                hardware ethernet 00:16:41:A7:C7:FC;
                fixed-address 192.168.2.14;
        }

I see now that I have a second device listed with the same IP address:

        host harriet {
                hardware ethernet 00:02:2D:1D:43:B6;
                fixed-address 192.168.2.14;
        }

This is actually an ancient Sony Picturebook (C1VFK),
my favourite laptop of all time, but one I thought was dead beyond revival.
However, I turned it on a few weeks ago
and was amazed to find that it seemed to function without problem.
I even updated it to Fedora 7 (it was running FC-5 when it died).
It only has the 256MB RAM (the maximum allowed) but runs KDE fine.

Anyway, that is beside the point.
But I suppose I may have confused my poor dhcpd with this double naming;
that would explain why it chose this strange interface.

I'm still not clear why it persists;
I'll try correcting dhcpd.conf and see if that changes things.
