Problemas con los NS

[electron83]

Hola buenas tardes/noches,

Hace tiempo compre un dominio y la semana pasada adquiri un plan de hosting sencillito (para empezar). Me he dirijido a la ficha de mi dominio y he cambiado los nameservers. La empresa en la cual me hospedo tiene nameservers bajo dos dominios. He probado con los primeros y tras cuatro dias aun no funcionaba, asi que me han dicho que me cambian a los otros a ver si me funcionan, acabo de cambiarlos.

Pero haciendo un DNS Report obtengo los mismos errores que antes, a ver si alguien sabe decirme que pasa (pongo solo los referentes a los NS):

WARN
All nameservers report identical NS records WARNING: At least one of your nameservers did not return your NS records (it reported 0 answers). This could be because of a referral, if you have a lame nameserver (which would need to be fixed).

xxx.xx.xxx.xx returns 0 answers (may be a referral)
xxx.xx.xxx.xx returns 0 answers (may be a referral)

FAIL
Lame nameservers ERROR: You have one or more lame nameservers. These are nameservers that do NOT answer authoritatively for your domain. This is bad; for example, these nameservers may never get updated. The following nameservers are lame:
xxx.xx.xxx.xx
xxx.xx.xxx.xx

FAIL
Missing nameservers 2 ERROR: One or more of the nameservers listed at the parent servers are not listed as NS records at your nameservers. The problem NS records are:
ns1.xxxxxxx.com.
ns2.xxxxxxx.com.

WARN
Nameservers on separate class C's WARNING: All of your nameservers (listed at the parent nameservers) are in the same Class C (technically, /24) address space, which means that they are probably at the same physical location. Your nameservers should be at geographically dispersed locations. You should not have all of your nameservers at the same location. RFC2182 3.1 goes into more detail about secondary nameserver location.

Espero que alguien pueda ayudarme pues soy un novato en el uso de dominios.

Muchas gracias.
