Your Knoppix boot probably pushed a dynamic DNS update via DHCP to
whatever hands out local DNS names on your LAN and now your local IP
is resolving to that name.

You probably need to update your hostname if you want it to be
something else.  dhclient (the DHCP client in CentOS 7) can also send
dynamic dns updates when configured.  (Look in the man page for
dhclient.conf, I believe it is do-forward-updates.)
