[Internet-e-architetture-di-rete] esercizio DNS, SMTP, HTTP

[Antonio Prado]

cari allievi,

per quest'anno siamo giunti al termine delle nostre conversazioni in aula.

vi lascio dunque con un'ultima proposta di esercizio.

quirinale.it
palazzochigi.it
agid.it
interno.it
esteri.it

per ciascuno di questi nomi a dominio individuare il RR IN MX
maggiormente prioritario e inviare un messaggio di prova all'indirizzo
di postmaster.

per ciascuno di questi nomi a dominio inviare le intestazioni HTTP.

formattare le risposte secondo questo modello:
