This host route is automatically set by ifconfig if you also supply it with a netmask (which is common) when you bind an IP address to your NIC

Why? Is something not working? That is a manual setting, but if you have to know; The network address will need to Hop from your network to your address. Then from your address to your default route. Its all about how the machine uses the MAC address.

Your routing table looks some what weired to me.
actually your destination subnet should have your IP address as gateway address.
all the routes learned WITH "uh" IS FOR the host .
specimen of routing table.

Destination Gateway Flags Refs Use Interface Pmtu PmtuTime
10.17.17.1 127.0.0.1 UH 52 556998 lo0 4608
127.0.0.1 127.0.0.1 UH 0 3839 lo0 4608
default 10.17.16.2 UG 39 1065426 lan2 1500
10.17.16.0 10.17.17.1 U 4 43094 lan2 1500

This bit:

127.0.0.1 127.0.0.1 UH 0 260158914 lo0 4136
145.78.106.70 145.78.106.70 UH 0 58877 lan0 4136

is normal, and automatically configured by the OS when you setup lan0.

Your config is "normal" for HP's.

It's there (your "145.78.106.70 145.78.106.70 UH 0 58877 lan0 4136") so processes on your machine that address your machines IP will stay on your machine without going to the wire (network).
