====== Network Documentation: Name Resolution and Connectivity ======

This section details the necessary commands to identify hosts by their IP address and perform data transfer tests in Windows environments.

===== 1. Name Resolution (Hostname) =====

To find the hostname associated with an IP address (10.56.88.20), use the following methods:

  * **Ping with Reverse Resolution:** Attempts to resolve the name during the echo test.
<code dos>
ping -a 10.56.88.20
</code>

  * **DNS Lookup (NSLookup):** Queries the configured DNS server directly.
<code dos>
nslookup 10.56.88.20
</code>

  * **Native PowerShell Command:** The most modern and detailed tool for DNS diagnostics.
<code powershell>
Resolve-DnsName -Name 10.56.88.20
</code>

===== 2. Web Transfer and Diagnostics (cURL) =====

A tool for interacting with web servers and verifying HTTP responses directly from the terminal.

  * **Basic Connection Test:**
<code dos>
curl http://10.56.88.20
</code>

  * **View Headers Only:** Useful for checking if a server is responding without downloading the full content.
<code dos>
curl -I http://10.56.88.20
</code>
