<br>
stasera abbiamo conversato degli spazi di indirizzamento IPv4 e IPv6:<br>
morfologia, notazione, subnetting.<br>
<br>
vi propongo ora qualche esercizio che mi raccomando di iniziare sin da<br>
subito finche' le idee sono fresche.<br>
<br>
dunque, come preannunciato, per ciascun indirizzo dato provate a<br>
calcolare inizio-rete, fine-rete e numero di host numerabili<br>
(considerato che in IPv4 non sono assegnabili agli host l'indirizzo di<br>
inizio rete e l'indirizzo di broadcast).<br>
<br>
faccio un esempio su come formattare l'esercizio:<br>
<br>
###########################<br>
1.<br>
Addr 1. 2. 3. 4<br>
Mask 255.255.255. 0<br>
<br>
Net 1.2.3.0<br>
Broadcast 1.2.3.255<br>
Hosts 2^8-2=254<br>
###########################<br>
<br>
ecco gli esercizi:<br>
<br>
per i cognomi da A a L:<br>
<br>
A-L.<br>
Addr 0. 1. 2. 3<br>
Mask 255.255. 0. 0<br>
Mask 255.254. 0. 0<br>
Mask 254. 0. 0. 0<br>
Mask 192. 0. 0. 0<br>
Mask 240. 0. 0. 0<br>
Mask 255.255.255.240<br>
Mask 255.255.255.252<br>
Mask 255.255.255. 1<br>
Mask 255.255. 64. 0<br>
Mask 255.255. 0.255<br>
<br>
per i cognomi da M a Z:<br>
<br>
M-Z.<br>
Addr 129.130.131.132<br>
Mask 255.255. 0. 0<br>
Mask 255.254. 0. 0<br>
Mask 254. 0. 0. 0<br>
Mask 192. 0. 0. 0<br>
Mask 240. 0. 0. 0<br>
Mask 255.255.255.240<br>
Mask 255.255.255.252<br>
Mask 255.255.255. 1<br>
Mask 255.255. 64. 0<br>
Mask 255.255. 0.255<br>
<br>
ovviamente, come al solito, chiunque puo' partecipare alla<br>
soluzione/discussione<br>
<br>
grazie<br>
