& 6 others
The Hosts file contains the mappings of IP addresses to host names. This file is loaded into memory (cache) at startup, then Windows checks the Hosts file before it queries any DNS servers, which enables it to override addresses in the DNS.

Je souhaitais revoir mes bases en réseaux, c'est pourquoi j'ai fait pas mal de recherches pour cela. Il existe de bons cours, de bons articles un peu partout, pas facile à trouve mais ça se trouve !
Je souhaite vous faire profiter des cours que j'apprécie tout particulièrement. Quand je parle "réseaux", c'est assez vaste, c'est pourquoi ce billet sera la première partie, il regroupera tous les liens vers des cours qui concernent toute la théorie de base (addressage IP, LAN, normalisations, TCP/IP, DNS, etc.)

MX Lookup Tool - Check your DNS MX Records online
by totoleheros
& 1 other
ABOUT MX LOOKUP
This test will list MX records for a domain in priority order. The MX lookup is done directly against the domain's authoritative name server, so changes to MX Records should show up instantly. You can click Diagnostics, which will connect to the mail server, verify reverse DNS records, perform a simple Open Relay check and measure response time performance. You may also check each MX record (IP Address) against 147 DNS based blacklists. (Commonly called RBLs, DNSBLs)
