if you know anybody at McAfee/Intel Cloud DNS team, could you pass
them contact to me or at least this message?

local.cloud.mcafee.com fails to respond to 0x20 DNS queries, but only
in a specific part of the QNAME.

b-0.19-23003008.1481.1518.19cf.3ea1.410.0.ekzijnekvvvg7gb38qcwur561b.avqs.mcafee.com. WORKS

B-0.19-23003008.1481.1518.19CF.3EA1.410.0.ekzijnekvvvg7gb38qcwur561b.avqs.mcafee.com. WORKS

b-0.19-23003008.1481.1518.19cf.3ea1.410.0.ekzijnekvvvg7gb38qcwur561B.avqs.mcafee.com. FAILS (with NXDOMAIN)

So only 0x20 changes in 'ekzijnekvvvg7gb38qcwur561b' label makes the query return NXDOMAIN
