If you really want to dot the i's and cross the t's you can add: 192.0.2.0/24 REJECT MX in IANA example network 198.18.0.0/15 REJECT MX in RFC 2544 benchmark network # IPv6 2001:db8::/32 REJECT MX in RFC3849 example network fc00::/7 REJECT MX in RFC4193 site local network ::1/128 REJECT MX in RFC4291 loopback network fe80::/10 REJECT MX in RFC4291 link local network 2001:200::/48 REJECT MX in RFC5180 benchmark network 100::/64 REJECT MX in RFC6666 discard-only network -- Viktor.
