[atlas] Odd queries from probe

While doing some debugging of my home network, I noticed some odd queries from the probe, namely this one: 02:28:36.921622 IP6 fe80::a2f3:c1ff:fec4:479f.51123 > 2001:558:feed::2.53: 23808+ A? 12920.atlas.ripe.net.b61065696c194ac3. (55) Is this some captive portal/wildcarding detection, or perhaps some other software issue? curious, - Jared
