command terminal 'ifconfig' returns value for eth1, '192...', but not '10...'.

yes, there is a configuration address 'http://192...' accessible via
web browser.

automatic dhcp. To check, the command 'drakconnect' was used to
activate the network configuration process; the default is automatic
ip (bootp/dchp) connection protocol

I think the ip address is determined by the isp; if the router is
switched off and then on, a new ip address is assigned.

yes, they differ by a digit

yes, 192...

yes
