Get the whole list:

<code>
wget ftp://ftp.ripe.net/pub/stats/ripencc/delegated-ripencc-latest
</code>

Parse it with the following script:

<code>
grep DK.ipv4 delegated-ripencc-latest | awk -F'|' -vOFS=/ '{print $4,32- log($5)/log(2)}' | while read network; do whois --verbose -h whois.ripe.net -T route -x $network >>danske_netblokke 2>&1; sleep 2; done
</code>

Now extract the IP subents:

<code>
cat danske_netblokke |grep route: | cut -d: -f2| sed 's/[[:space:]]//g'
</code>




One-liner for DK:
<code>
curl --silent https://stat.ripe.net/data/country-resource-list/data.json?resource=dk |grep -Eo  '(25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)\.(25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)\.(25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)\.(25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)\/([0-9]|[1-3][0-9])'| column -c 280

</code>

Change the resource=xx to the country you would like to extract (https://en.wikipedia.org/wiki/ISO_3166-2). 

The last part "column -c 280" can be excluded to get the list in one row.
