Same for me, only I see the IPv4 NS hosts in 185.203.204/22:

    @a.ns.as57335.net.[185.203.204.10]
    @b.ns.as57335.net.[185.203.205.10]
    @c.ns.as57335.net.[185.203.206.10]
    @d.ns.as57335.net.[185.203.207.10]
    ;; connection timed out; no servers could be reached

    @a.ns.as57335.net.[2a0c:d2c0::53:5:7335]
    @b.ns.as57335.net.[2a0c:d2c2::53:5:7335]
    @c.ns.as57335.net.[2a0c:d2c4::53:5:7335]
    @d.ns.as57335.net.[2a0c:d2c6::53:5:7335]
    ;; connection timed out; no servers could be reached

The delegation and glue RRs from .net were:

    as57335.net. IN NS a.ns.as57335.net.
    as57335.net. IN NS b.ns.as57335.net.
    as57335.net. IN NS c.ns.as57335.net.
    as57335.net. IN NS d.ns.as57335.net.
    ;
    a.ns.as57335.net. IN A 185.203.204.10
    a.ns.as57335.net. IN AAAA 2a0c:d2c0::53:5:7335
    b.ns.as57335.net. IN A 185.203.205.10
    b.ns.as57335.net. IN AAAA 2a0c:d2c2::53:5:7335
    c.ns.as57335.net. IN A 185.203.206.10
    c.ns.as57335.net. IN AAAA 2a0c:d2c4::53:5:7335
    d.ns.as57335.net. IN A 185.203.207.10
    d.ns.as57335.net. IN AAAA 2a0c:d2c6::53:5:7335
