Ake packety? Pokial viem, tak DHCP iba odpoveda na poziadavky klientov,
ziadnu komunikaciu neinicializuje.
Navyse som mu tam kazal dat ignoraciu vsetkych neznamych klientov
ako aj prazdny zaznam, takze na ziadne poziadavky odpovedat nebude.

Je celkom mozne, ze riesenie s prazdnym zaznamom zaberie viac pamate,
ale ine nevyhody v tom nevidim. Navyse kod bude mozno jednoduchsi,
kedze sa moze program bindnut na adresu 0.0.0.0 a nemusi urobit bind
na vsetky eth rozhrania.
