"glue at root" - sounds like a gardening tip. :-)

Really, they probably mean that there's no glue record for your
server in the parent zone. If you had the tool check "joyworld.com",
then I'd guess it's talking about "dns12.dion.ne.jp", the second
server listed in the delegation. In which case, no, there isn't a
glue record in the gTLD servers - there shouldn't be.

Some people don't get glue records. They think that the parent zone
should have an A record for every name server used in the delegation
records for a child zone. This is only true if the name server's name
is descended from the name of the child zone itself. For example,
here's a quiz:
____________________________________________________________________

Suppose the following are zones:

com
menandmice.com
sales.menandmice.com

and suppose the delegation records for menandmice.com were:

menandmice.com. NS ns.menandmice.com.
menandmice.com. NS ns.sales.menandmice.com.
menandmice.com. NS dns12.dion.ne.jp.

What glue records should also be present? Justify your answer.
___________________________

Answer:

ns.menandmice.com. A ip.add.re.ss
ns.sales.menandmice.com. A other.address

These two servers have names that end in the name of the delegated
zone, menandmice.com. The third server's name doesn't end in com, so
if the com administrator tried to put an A record for this server
into the zone, that would cause an error message and the zone might
not load.
____________________________________________________________________

OK, let's talk about the other two problems. It appears that neither
of the servers for joyworld.com have an authoritative version of the
zone. Are you even able to get mail? Wait, don't answer that... ;-)

I didn't find any MX records for joyworld.com (as implied by the
previous paragraph), but in general, any name used in the data
portion of an MX record should resolve to an IP address (i.e. it
should have an A record), and that IP address should have exactly one
PTR record, and that PTR record should point back to the name used in
the MX record. Get all that?
