<p>When running <code>getpeerinfo</code>, most nodes show a standard <code>addr</code> like this:</p>

<pre><code>95.121.82.153:8333
</code></pre>

<p>But the <strong>first inbound connection</strong> has a differently formatted <code>addr</code> like this:</p>

<pre><code>[2a01:4f8:212:3b1f::2]:32220
</code></pre>

<p>What does this mean?</p>

When running a full node, why does the first inbound node have an unusual IP?

When running `getpeerinfo`, most nodes show a standard `addr` like this:

```
95.121.82.153:8333

```

But the **first inbound connection** has a differently formatted `addr` like this:

```
[2a01:4f8:212:3b1f::2]:32220

```

What does this mean?

That's an [IPv6 address](https://en.wikipedia.org/wiki/IPv6_address). Basically, it's the latest version for formatting/assigning IP addresses. At some point, we should all be seeing a lot of those...but they've been saying that for years.
