Simple if/elseif structure. I sure you could use tables/data group, but I never used them, so I don't know how.

if {[IP::addr [IP::client_addr]/16 equals 172.16.0.0]} {
    pool POOL1
} elseif {[IP::addr [IP::client_addr]/16 equals 172.17.0.0]} {
    pool POOL2
} elseif {[IP::addr [IP::client_addr]/16 equals 172.18.0.0]} {
    pool POOL3
} else {
pool DEFAULT
}
