nie je mi jasne kto ma ukoncit takuto komunikaciu server alebo client, niekde na inet-e som cital, ze server by nemal ponukat IP klientovi s rovnakym DIUD ale inym IAID (neviem vsak ci je to pravda a ak ano ako to nastavit)
podla mna server by po "Decline received." mohol aspon na "default-lease-time"
Vie niekto ako to riesit ?

"drtiva vetsina zarizeni dhcp6 vubec nepodporuje"
vlastna skusenost, alebo su aj nejake vyjadrenia tvorcov OS ?
mne sa zda, ze linux, w10 aj macos to podporuje dobre pokial mam jednu sietovku
"... A ty adresy kupodivu a prekvapive pak jsou kolizni."
podla mna ani nie, po prideleni adresy jednemu rozhraniu a dalsej ziadosti o ipv6 server nemoze vediet, ci client dany interface neodpojil, ina situacia je po "DECLINE", vtedy server podla mna by mal prideli nieco z range .... Samozrejme client sa nemoze zlozit (ako macos) ak je server "neoblomny"
"DHCP6 bylo odjaziva planovano k tomu, aby pridelovalo rozsahy."
je ktomu nejaka teoria (RFC...)
Dakujem.
