            <p>We provide some anycast services over IPv6.</p>

<h2 id="anycast-address-space">Anycast address space</h2>

<p><strong>fd42:d42:d42::/48</strong> is reserved for anycast services.</p>

<p>Each anycast service runs on a dedicated /64 in this range.  This way, nobody needs to update filters.</p>

<p>Remember, if you announce an anycast /64, then you need to provide <strong>all</strong> services within this /64. It’s probably simpler to only provide one service for each /64.</p>
