i suppose thats weird according to my network classes hehehe ..
if ur ISP change ur ip .. as its dhcp as most of ISP's are .. then i dunno u will have different ip and hence /etc/hosts entry wont exist
wot did u put in /etc/hosts ...wot entry ? ip given by ISP to u ? again its network thing ..
are u sure ur ISP give only dynamic IP .. coz it might be possible u have a static ip .. does ur ip change on every connect to internet .. or maybe after every boot ?
if it doesnt .. its probably static .. and then it was wise thing to do ..
I AM MAJORLY CONFUSED .... heh sorry .. cudnt help u much ...
thnks for the link
all the best
