2. Addressing: IPv4: 32-bit, written as decimal bytes e.g. 24.123.54.77
IPv6: 128-bit, written as hex words e.g. fe80::21f:3bff:fed2:afe9
Leading zeros may be dropped, zero words may be dropped
0000::1/128 Localhost
2000::/ Global Unicast
FC00::/ Unique Local Unicast
FE80::/ Link Local Unicast
FF00::/ Multicast
- everything else reserved by IANA
- no broadcasts

3. IPv6 vs IPv4 : RFC 2460 - simpler headers - flow labelling
- authentication
- no fragmentation by routers
- minimum MTU of 1280, MTU discovery recommended
- IPsec
- EUI 64-bit global identifier (by manufacturer ID, like MAC)
- multicast, not broadcast

4. 6in4 Tunnels Freenet6 @ gogo6.com SixXS @ sixxs.net
- build gw6c binary
- automated signup
- single tunnel or subnet
- spawns radvd
- POP in Montreal
sixxs.net
- aiccu included in distro
- manual signup
- single tunnel or subnet
- manual config
- POP in Chicago

5. Stateless Autoconfiguration – RFC 4862
- router advertisement daemon radvd advertises prefix on multicast
- client kernel creates address
DHCPv6 may be used to get DNS etc.

6. Accountability, Auditing
- multiple addresses per host
- arpwatch -> ndpmon
- addresses may not be in DNS
- MAC address logging for accountability
- IEEE 802.1x – network access control
