I admit I was playing with the routing table, trying to learn it, but now
the fun is over because I screwed up and just want to get back to 'normal'.

My network is "normal" in that:
a. My router is 192.168.1.1
b. My desktop is 192.168.1.14 == it's dhcp but that's what it is below
c. I know that 192.168.1.0 & 192.168.1.255 are "special"
d. And that 127.0.0.1 is the "localhost" (and 127.0.0.0 must be "special")
e. And that a netmask of 255's is all 1's (in binary)
f. And that the "gateway" is just the "router" (of 192.168.1.1 below)
g. And that 192.168.1.255 & 127.255.255.255 are "special" (somehow)
h. And that 255.255.255.255 (not as a netmask) must also be "special"

But ... what the heck are these numbers doing in the routing table below?
A. 192.168.56.0 & 192.168.56.1 & 192.168.56.255 ?
B. 224.0.0.0 ?
C. 127.255.255.255.255 ?

As admin, I tried to clear up the mess using:
route delete *
and
route -f

This gets me the following immediately thereafter:
route print

But when I reboot, this always comes up:

Assuming a "normal" home setup, with a router at 192.168.1.1 and with the
router handing out addresses dynamically, what *should* my "route print"
look like and how do I get *back* to the defaults?
