Imenno tova pitah, 
tova znachi che ako ne pravish proverka chesto za tova dali 
ima avtomatichno dobaveni entryta v ARP tablicata , az ot 
strna na "hitrec" shte moga da si smenia IP-to i da rabotia 
do sledvashtia pyt kogato si pochistish dinamichno 
dobavenoto entry (t.e. pri restart na mashinata).
Ako tova se pravi na 1 minuta (t.e. flushvane na dinamichno 
dobavenite zapisi v ARP tablicata) az pyk moga da si 
napravia script s koito dinamichno si promeniam IP to da 
kajem na vremeto na koeto ti pochistvash tablicata.
Za tova mi beshe vyrposa za niakakyv trik s koito shet 
mojesh izcialo da zabranish dinamichnoto dobaviane na 
entryta v ARP tablicata.
