Minor wish: it would be much more common to allow to exclude v4 ip ranges by using the addr/mask notation, or even A.B.*.* class notation.

You may use these

wget -qO- "https://www.cloudflare.com/ips-v4" \
 | xargs -n1 sipcalc | sed -n 's|^Network range\s\+- \(.\+\) - \(.\+\)$|\1-\2|p' \
 | xargs -n1 bash -c 'echo -n " --exclude-ip=$0"'

wget -qO- "https://my.pingdom.com/probes/ipv4" \
 | xargs -n1 bash -c 'echo -n " --exclude-ip=$0"'

wget -qO- "https://ip-ranges.amazonaws.com/ip-ranges.json" \
 | jq -r ".prefixes[].ip_prefix" \
 | xargs -n1 sipcalc | sed -n 's|^Network range\s\+- \(.\+\) - \(.\+\)$|\1-\2|p' \
