Bash script for checking if a host is on the local network
I'm trying to write a script that allows you to enter your machine name, and then lets you know if the host is on the local network. Here's what I have:
This allows me to enter my machine name (ubuntu) but doesn't actually let you know if it's on the local network or not (aside from looking at the IP and knowing that it's local).
I asked my TA for advice and after a week, his only response was 'ruptime.'
I'm not too sure how to incorporate that into a script that does what the question is asking. Any help or advice would be appreciated. Thanks!

routes
routes(4) Kernel Interfaces Manual routes(4)NAME
routes - Specifies Internet routing information to the routing tables
SYNOPSIS
/etc/routes
DESCRIPTION
Static routes can be defined in the /etc/routes file. The /etc/routes file identifies static routes that are automatically added to the
network routing tables with the /usr/sbin/route add command. The /sbin/init.d/route script contains the /usr/sbin/route add command that
is executed for each entry in the /etc/routes file when the network is restarted on the system or the system is rebooted.
The general format of an entry in the /etc/routes file is: Dest Name1 Name2
The following is a brief description of each element in an /etc/routes file entry: A keyword that indicates whether the route is to a net-
work or to a host. The two possible keywords are -net and -host. The name or address of the destination network or host. Name1 can be
either a symbolic name (as used in the /etc/hosts or /etc/networks file) or an Internet address specified in dotted-decimal format. The
name or address of the gateway host to which messages should be forwarded. Name2 can be either a symbolic name (as used in the /etc/hosts
file) or an Internet address specified in dotted-decimal format.
The routes file is a Context-Dependent Symbolic Link (CDSL) and must be maintained as such. See the System Administration manual for more
information.
EXAMPLES
To specify a route to a network through a gateway host with an entry in the /etc/routes file, enter:
-net net2 host4
This example specifies a route to a network, net2, through the gateway host4. To specify a route to a host through a gateway host
with an entry in the /etc/routes file, enter:
-host host2 host4
This example specifies a route to a host, host2, through the gateway host4. To specify a route to a default gateway host with an
entry in the /etc/routes file, enter:
default 130.9.0.5
This example specifies a route to a default gateway with an Internet address of 130.9.0.5.
FILES
