Glue for NS records

[claretta]

Ciao,

ho sistemato i nameserver di alcuni domini, va tutto bene ma resta sempre
questo avviso:

Glue for NS records INFO: GLUE was not sent when I asked your nameservers
for your NS records.This is ok but you should know that in this case an
extra A record lookup is required in order to get the IPs of your NS
records. The nameservers without glue are:
xxx.xxx.xxx.xxx (IP)
You can fix this for example by adding A records to your nameservers for the
zones listed above.

Non riesco a capire cosa c'� ancora da fare... � grave?

in pratica che devo fare? io ho fatto per ora cos� (IP di fantasia)

ns1.nameserver.com = 123.456.789.001
ns2.nameserver.com = 123.456.789.002

Configurazione su PLESK per nameserver.com:

123.456.789.001 / 24 PTR nameserver.com.
nameserver.com. NS ns1.nameserver.com.
nameserver.com. NS ns2.nameserver.com.
nameserver.com. A 123.456.789.001
ftp.nameserver.com. CNAME nameserver.com.
ns1.nameserver.com. A 123.456.789.001
ns2.nameserver.com. A 123.456.789.002
www.nameserver.com. CNAME nameserver.com.

(Questo va bene, tutti i controlli sono OK)

Configurazione su PLESK per dominio.xx:

dominio.xx. NS ns2.nameserver.com.
dominio.xx. NS ns1.nameserver.com.
dominio.xx. A 123.456.789.001
123.456.789.001 / 24 PTR dominio.xx.
ftp.dominio.xx. CNAME dominio.xx.
www.dominio.xx. CNAME dominio.xx.

Zona Master, creata da PLESK su server 123.456.789.001:

zone "dominio.xx" {
type master;
file "dominio.xx";
allow-transfer {
123.456.789.001;
common-allow-transfer;
};
};

Zona Slave, creata manualmente su server 123.456.789.002:

zone "dominio.xx" {
type slave;
file "slave/dominio.xx";
masters {
123.456.789.001;
};
allow-transfer {
123.456.789.002;
common-allow-transfer;
};
};

dominio.xx tutto ok tranne per l'avviso:

"INFO: GLUE was not sent when I asked your nameservers for your NS

lookup is required in order to get the IPs of your NS records. The
nameservers without glue are:
