Dette er med utgangspunkt i diskusjon om tap av laptop,
og hvorvidt det er mulig å sende mac adresser med ut mot internett..
Vi er for det meste alle enig om at mac-hardware adressene til nettverkskortet ikke sendes forbi ens Lokale IP-nett.
Men selv mener jeg å ha sett eksempler på at det i tilfeller kan skje..
Slete litt med å finne noe 'informativ info' på dette i morgentimene. (og jeg jeg er litt trøtt etter våkenatt
Men synes dette utdraget fra RFC-919 forteller noe interessant..
Er det sånn å forstå at former for Broadcast trafikk KAN sendes ut mot nettet?
(Iallefall til serverne for hver ISP.. )
----------------
- Broadcast to all hosts on a remote IP network: It is
occasionally useful to send a broadcast to all hosts on a
non-local network; for example, to find the latest version of a
hostname database, to bootload a host on an IP network without a
bootserver, or to monitor the timeservers on the IP network.
This case is the same as local-network broadcasts; the datagram
is routed by normal mechanisms until it reaches a gateway
attached to the destination IP network, at which point it is
broadcast. This class of broadcasting is also known as "directed
broadcasting", or quaintly as sending a "letter bomb" [1].
- Broadcast to the entire Internet: This is probably not useful,
and almost certainly not desirable.
For reasons of performance or security, a gateway may choose not to
forward broadcasts; especially, it may be a good idea to ban
broadcasts into or out of an autonomous group of networks.

Håper noen Broadcast/mac-adresse guruer kan forklare meg dette litt med teskje
Hvilke typer ADSL tjenester / devicer som støtter dette feks..
Ciao!
