 		More frightening, adding Lightning support to your wallet or system introduces new reliance on uncensorability of the P2P network, <a href="https://lists.linuxfoundation.org/pipermail/lightning-dev/2019-December/002369.html">with several new avenues for attack which even Bitcoin Core likely doesn't fully protect against.</a>

-			bitcoinheaders.net exists to help provide one more, diverse, source of Bitcoin blockchain data - this time using the DNS. By fetching headers and/or neutrino filters from as many sources as possible, you can start to build reliable detection of censorship-based attacks. While this still leave mitigation of the attacks to be developed, detection is always the first step.

 			bitcoinheaders.net currently supports fetching of either full Bitcoin headers or neutrino filter headers, both with a similar format. To ensure reliable access in the face of strict DNS filters, the data is encoded in IPv6 addresses in AAAA records and DNSSec signed to prevent some basic attacks.
 		</p>
+		<p>
+			Headers names are broken into sub-zones of 10,000 records, so queries should take the form of height.(height / 10000).bitcoinheaders.net (or, for basic neutrino filter headers, height.(height / 10000).basic.filter.bitcoinheaders.net).
+		</p>
 		<p>
 			All headers and filter headers are encoded with an arbitrary two byte prefix (currently "2001:"), followed by a 0-indexed order nibble (as nameservers often reorder responses). Bitcoin headers are then prefixed by a single 0 byte (two 0 nibbles) and placed into the remaining 80 bytes of six IPv6 addresses. Filter headers are simply placed into three IPv6 addresses with a 17-nibble (8.5 byte) 0 suffix.
