Is there any way to configure iptables to ACCEPT the traffic from 10.anything?

currently I have the rule to the single address, but I want the entire range:

sudo iptables -I INPUT --src 10.240.74.164 -m tcp -p tcp --dport 80 -j ACCEPT

How would I need to change my above rule?

Any help would be appreciated.

You can simply write this:

iptables -I INPUT -s 10.0.0.0/8 -p tcp --dport 80 -j ACCEPT

Source and destination rules accept CIDR notation. Also, -m tcp is usually implicit (though including it is harmless), and -s is acceptable shorthand for --src.
