[SOLVED] What is 12h when seen after address ranges?

Post by otacon14112 »

I know what netmasks are, and CIDR notation, ie 192.168.2.4/24, but in IP address ranges, such as dnsmasq.conf:

Code: Select all

dhcp-range=lan,192.168.1.100,192.168.200,12h
dhcp-lease-max=100
Is it a maximum of 12 hosts, spanning 100 IP addresses, or hops? I've seen it other places, too.

From dnsmasq.conf

Code: Select all

# Uncomment this to enable the integrated DHCP server, you need
# to supply the range of addresses available for lease and optionally
# a lease time. If you have more than one network, you will need to
# repeat this for each network on which you want to supply DHCP
# service.
#dhcp-range=192.168.0.50,192.168.0.150,12h
No doubt it's the optional lease time.

Thanks, I'm not accustomed to seeing it provided in that way. It makes sense now that you pointed it out.
