Static Leases on Different VLANs

I am trying to set up two different VLANs on one router and give all the devices on each VLAN static leases for their IP addresses via DHCP. This I think makes them easier to identify by IP address when monitoring traffic with nlbwmon.

The following is an example of what I have in my dhcp config file

click here for:- /etc/config/dhcp

config dnsmasq
option domainneeded '1'
option boguspriv '1'
option filterwin2k '0'
option localise_queries '1'
option rebind_protection '1'
option rebind_localhost '1'
option local '/lan/'
option domain 'lan'
option expandhosts '1'
option nonegcache '0'
option authoritative '1'
option readethers '1'
option leasefile '/tmp/dhcp.leases'
option resolvfile '/tmp/'
option localservice '1'

config dhcp 'lan'
option interface 'lan'
option start '100'
option limit '150'
option leasetime '12h'
option dhcpv6 'server'
option ra 'server'
option ra_management '1'

config dhcp 'wan'
option interface 'wan'
option ignore '1'

config odhcpd 'odhcpd'
option maindhcp '0'
option leasefile '/tmp/hosts/odhcpd'
option leasetrigger '/usr/sbin/odhcpd-update'

config dhcp 'vlan1'
option start '100'
option leasetime '12h'
option limit '150'
option interface 'vlan1'

config host
option dns '1'
option name 'lubuntu01'
option mac '60:E3:27:20:A8:56'
option ip ''

config host
option dns '1'
option name 'lubuntu02'
option mac '00:1F:16:2B:78:ED'
option ip ''

And it seems to be working, however, I was wondering if the "config host" entries should be tied to the vlan somehow?
Once I put this router into production it will have many of hosts on each VLAN so I just wanted to check before setting up the multiple "config hosts" entries.
