Both the 192.168 & 169.254 are private addresses for LAN use.  I
wouldn't call either of them self-referring (like 127.0.0.1 is).

The 192.168 range being manually or DHCP assigned.

The 169.254 range being randomly assigned in the absence of manual or
DHCP configuration, known as link-local, bonjour or ZeroConf addressing.
If you don't use them (and you shouldn't other than for ad-hoc
client-only networks without any sort of server), you can turn off those
services, and you'd be free to delete them from routing tables.

The link-local scheme can be confusing for people, as their computer can
appear to have a functioning network, simply because the interface came
up with an address, but not actually have a functioning network, because
they're using an address that's not on the same sub-net as the rest of
their equipment.  Unless you're familiar with the IP range, and actually
look at the IP that you've got, it won't be obvious what the problem is.

Don't send private replies to my address, the mailbox is ignored.  I
read messages from the public lists.
