Hello,

I am wondering if anyone can point me to who manages the .BE ccTLD.  We are seeing one of their NS performing referrals on DS query when performing DNSSEC validation and it is causing some issues.

Here are their NS:

BE.                     86400   IN      NS      a.ns.dns.BE.
BE.                     86400   IN      NS      b.ns.dns.BE.
BE.                     86400   IN      NS      c.ns.dns.BE.
BE.                     86400   IN      NS      x.dns.BE.
BE.                     86400   IN      NS      london.ns.dns.BE.
BE.                     86400   IN      NS      prague.ns.dns.BE.
BE.                     86400   IN      NS      brussels.ns.dns.BE.
BE.                     86400   IN      NS      amsterdam.ns.dns.BE.

The one we are seeing issues for is:  x.dns.BE.

The others are acting as expected:

Any help would be most appreciated.
