Hi Daniel,
you find mostl of you questions answered in "man netstat" (the
relevant passage is posted below)
The missing part is the expiry, which IMHO are the seconds, the ARP
entry is valid (after this time a new arp request would be issued)
I hope this is the information you needed.
br,
Robert

The routing table display indicates the available routes and their sta-
tus. Each route consists of a destination host or network, and
a gateway
to use in forwarding packets. The flags field shows a
collection of
information about the route stored as binary choices. The
individual
flags are discussed in more detail in the route(8) and route(4)
manual
pages. The mapping between letters and flags is:
1 RTF_PROTO1 Protocol specific routing flag #1
2 RTF_PROTO2 Protocol specific routing flag #2
3 RTF_PROTO3 Protocol specific routing flag #3
B RTF_BLACKHOLE Just discard pkts (during updates)
b RTF_BROADCAST The route represents a broadcast address
C RTF_CLONING Generate new routes on use
c RTF_PRCLONING Protocol-specified generate new routes on
use
D RTF_DYNAMIC Created dynamically (by redirect)
G RTF_GATEWAY Destination requires forwarding by
intermediary
H RTF_HOST Host entry (net otherwise)
L RTF_LLINFO Valid protocol to link address translation
M RTF_MODIFIED Modified dynamically (by redirect)
R RTF_REJECT Host or net unreachable
S RTF_STATIC Manually added
U RTF_UP Route usable
W RTF_WASCLONED Route was generated as a result of cloning
X RTF_XRESOLVE External daemon translates proto to link
address
Direct routes are created for each interface attached to the
local host;
the gateway field for such entries shows the address of the
outgoing
interface. The refcnt field gives the current number of active
uses of
the route. Connection oriented protocols normally hold on to a
single
route for the duration of a connection while connectionless
protocols
obtain a route while sending to the same destination. The use
field pro-
vides a count of the number of packets sent using that route.
The inter-
face entry indicates the network interface utilized for the route.

Flags,Refs,Use,Expire
In Flags: UGS, UC, UHLW, UH
Somebody can explain me ?
Thanks,
