Hi. About routers: Have I understood right: If for example oops moves for different network and it gets new IP-address, I don't need every oops' ip-address in routers /etc/hosts -file and only first one is needed? Like when for example oops' IP-address is in startup 3ffe::4 and crashs 2ffe::1, router who is between oops and crash needs in /etc/hosts -file: 127.0.0.1 localhost.localdomain localhost 2ffe::1 oops.something.fi oops 3ffe::4 crash.something.fi crash And also in oops' and/or hosts /etc/hosts -file only first (other HIP-machines) IP-address needed? Am I talking nonsense? -Teemu Väisänen
