Well，the owner may not want to update secret key just to change her/his ip with time passing, updating secret key frequently is bothersome. An optional date/time can add more flexibility, if the owner wishes to obtain a constant IP, the date/time can be ignored, if the owner wants to change IP once a year, the date/time can be chosen the year,...... > > Thanks, > -- > Fernando Gont > SI6 Networks > e-mail: [email protected] > PGP Fingerprint: 6666 31C6 D484 63B2 8FB1 E3C4 AE25 0D55 1D4E 7492 > > > >
