That's overkill.

Since I already ignore target hosts in a file that lists known
unroutable networks, network addresses and broadcast addresses, I just
include wildcarded host addresses in that file:

-- In Exim configure file:
lookuphost:
  driver = dnslookup
  domains = ! +local_domains
  ignore_target_hosts = /usr/local/etc/exim/unroutable-nets
  transport = remote_smtp
  no_more

-- In unroutable-nets file:
# List of hosts and/or networks which are known to be unroutable and to
# which it therefore does not make sense to attempt SMTP deliveries.
#
# WARNING!  Don't just deploy this without consideration.
#
# You may be using some of these (e.g. 10.0.0.0/8) for private networks,
# in which case you'll want to remove them from the list and just
# include the network and broadcast addresses (e.g. 10.0.0.0/32 and
# 10.0.0.255/32).

0.0.0.0/8
10.0.0.0/8
127.0.0.0/8
169.254.0.0/16
172.16.0.0/12
