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!

ruptime
ruptime(1) General Commands Manual ruptime(1)NAME
ruptime - Displays the status of each host on a network
SYNOPSIS
ruptime [-ar] [-l | -t | -u]
ruptime [-ar] [-l | -t | -u] [machinename]
The ruptime command displays the status of each host on a local network that is running the rwhod daemon.
If machinename is specified, only the status of that machine is displayed.
OPTIONS
Includes all users. Without this option, users whose sessions are idle an hour or more are not included. Sorts the list by the load aver-
age over 5-, 10-, and 15-minute intervals prior to a server's transmission. The load averages are multiplied by 10 to represent the value
in decimal format. Reverses the sort order. Sorts the list by the length of uptime. Sorts the list by the number of users.
DESCRIPTION
The status lines are sorted by hostname unless the -l, -t, or -u option is indicated. The status information is provided in packets broad-
cast once every 3 minutes by each network host running rwhod. Any activity (such as the power to a host being turned on or off) that takes
place between broadcasts is not reflected until the next broadcast. Hosts for which no status information is received for 11 minutes are
reported as down.
EXAMPLES
To get a status report on the hosts on the local network, enter: $ ruptime
Information similar to the following is displayed: host1 up 5:15, 4 users, load 0.09, 0.04, 0.04
host2 up 7:45, 3 users, load 0.08, 0.07, 0.04 host3 up 2:28, 0 users, load 0.01, 0.02, 0.03
host4 up 3+01:44, 1 user, load 0.01, 0.02, 0.03 host7 up 7:43, 1 user, load 0.06, 0.12, 0.11
(Output may be formatted differently on your system.) To get a status report sorted by load average, enter: $ ruptime -l
Information similar to the following is displayed: host2 up 7:45, 3 users, load 0.08, 0.07, 0.04
host1 up 5:18, 4 users, load 0.07, 0.07, 0.04 host7 up 7:43, 1 user, load 0.06, 0.12, 0.11
host3 up 2:28, 0 users, load 0.01, 0.02, 0.03 host4 up 3+01:44, 1 user, load 0.01, 0.02, 0.03
(Output may be formatted differently on your system.)
FILES
