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.

The genesis block header is, thus, encoded as (note that the responses are usually not sorted):
<p class="hex">

It should go without saying that this should only be used as a backup chain source, never as the primary chain source.
