+define Package/ipset-dns/description
+ The ipset-dns daemon is a lightweight DNS forwarding server that adds all
+ resolved IPs to a given netfilter ipset. It is designed to be used in
+ conjunction with dnsmasq's upstream server directive.
+
+ Practical use cases include routing over a given gateway traffic for
+ particular web services or webpages that do not have a priori predictable
+ IP addresses and instead rely on dizzying arrays of DNS resolutions.
