What will that tell you? You want SMTP which are probably not the same
as their MX records. You probably won't be getting any mail from their
MX. Some of what they had sent me as IP blocks with legit SMTP servers
were:
# Biz
24.30.199 OK
24.30.200 OK
24.30.201 OK
24.30.203 OK
24.30.205 OK
# Herndon
24.30.204 OK
24.30.211 OK
24.30.218 OK
and a lot more like that.
Unfortunately they mix in valid SMTP with DHCP so there's no simple
naming convention to use like *.smtp.rr.com which would make life a lot
easier. Or giving DHCP customers all IPs with rDNS ending *.dhcp.rr.com.
