Depletion of IPv4
2001:470:1f05:d37:202c:7674:c4c2:4fa8
Each : divides the address along 16-bit boundaries
And the address is represented in HEX

MAC address: F0-DE-F1-5B-B3-24
Take MAC and split it, stuff in FF:FE and flip the 7th bit
A network prefix such as 2001:db8::/64
Is saying the following :
2001:0db8:0000:0000:0000:0000:0000:0000/64
| network portion |  host portion

Notice there are no global DNS Servers
Notice there is no FQDN information
2001:470:82a9:7:41a6:5976:37ac:4f54 is from DHCPv6
2001:470:82a9:7:202c:7674:c4c2:4fa8 is from SLAAC
2001:470:82a9:7:3d1f:ad49:ee12:4880 is from SLAAC
2001:470:1f05:d37::/64 gets a permanent and temporary
2001:470:82a9:7::/64 gets a permanent and temporary
