ipv4 basics |
32-bits dotted decimal binary 192.168.2.1 {192 or 1100000} octect, 8 bits each |
|
|
Ipv6 basics |
128 bit hexideciaml 0-9 , A-F 1111.2222.3333.4444.5555.6666.7777.8888.9999.0000.AAAA {1111} hextect(16 bits each) |

Ipv6 compression rule 1 |
0fac.f395.1f69.bacd.daca.0703.0394 ^ ^ ^ f4c 703 394 |

|
Ipv6 compression rule 2 |
0fac:0347:0000:BEAB:0000:0000:deaf:0111 compressed -> FAC:347:0:BEAB::DEAF:111 |
|
|
categories of Ipv6 |
*Unicast addresses. A packet is delivered to one interface. *Multicast addresses. A packet is delivered to multiple interfaces. *Anycast addresses. A packet is delivered to the nearest of multiple interfaces (in terms of routing distance). |
|
|
ipv6 addresses |
link local-sends withing local link loop back-sends packet to itself all bits but last bits are 0s mainly for testing and verifying unspecified address-all 0s, used as source when device has no ipv6 assigned and is still connected via DHCP but still needs to communicate unique local -used for private addressing among websites for ex global addresses = /64 |
|
|
/64 and ipv6 details |
{0fac:0347:0000:}{BEAB:}{0000:0000:deaf:0111} global subnet interface ID routing ID prefix |
|
|
SLACK |
device will get address from slack when no DHCP is available |
|
|
EUI64 |
generating a 64 bit address based on the Mac-address, just stuck fffe in the middle of mac then conver for 6bits to binary, 7th is fliped, then back to hex used when you cant communicate with DHCP server and slack isnt running on the router |
|
|
NDP |
Equivalent to ARP for ipv4- discovers ip addresses |
|
|
header in PDU |
contains source and destination ports |
|
|
add on header which contains |
source and destination IPs that tells us if we are connected to a host or a network |
|
|
the frame is added |
contains mac address |
|
|
next step for pdu |
the frame is encoded into a stream of bits |
