9.1 Key Terms
amplification
attack = A method of attack that starts with relatively few packets and
amplifies its responses (like Smurf or Fraggle attacks).
RS
= IPv6 router solicitation request. Used by an IPv6 device to obtain
information from an IPv6 router on the local network.
RA
= IPv6 router announcement. Used by a router to inform other IPv6 devices about
the local network address to which they are connected.
NS
= IPv6 neighbor solicitation. Used by an IPv6 speaker to make a request of one
or more local IPv6 devices on the same network.
NA
= IPv6 neighbor advertisement. Used to communicate information from an IPv6
host to another on the same locally connected network.
Eavesdropping
= Any method of listening in on other conversations, whether voice or data
(sniffer).
man-in-the-middle
attack = A form of eavesdropping where the attacker inserts himself in
the middle of a conversation, masquerading as a wireless access point, router,
proxy server, or so on.
spoofing
= An attack where the source pretends to be another host or user (MAC, IP,
email).
EUI-64
= Extended Unique Identifier-64, an IEEE standard for converting a 48-bit MAC
address into a 64-bit host address in IPv6 networks. Used for stateless
autoconfiguration.

Hexadecimal
Decimal = Binary =
Hexadecimal
0 = 0000 = 0

2 = 0010 = 2
3 = 0011 = 3
4 = 0100 = 4
5 = 0101 = 5
6 = 0110 = 6
7 = 0111 = 7
8 = 1000 = 8
9 = 1001 = 9
10 = 1010 = A
11 = 1011 = B
12 = 1100 = C
13 = 1101 = D
14 = 1110 = E
15 = 1111 = F
