Is your network setup so chaotic that you don't know what address
chunks are allocated by DHCP or PPP?  They're not asking you to
aggregate your printers, they're just asking which ranges are dynamic,
since mail directly from dynamic ranges is about 99.999% bot spam.

If you really don't know what's dynamic, I can't say I blame them
for assuming the worst.

R's,
