 ====== Network Testing ======
+===== Route Tracing =====
+==== Using TCP ====
+:!: May require ''sudo''...
+  * Requires something listening on the port you specify
+    * For example a web server listening on port 443 (SSL)
+  * Use ''-n'' to eliminate name resolution
+    * Faster
+  * Uses TCP SYN and ACK instead of ICMP
+Using port 443:
+<file>
+traceroute -T -O info -p 443 hostname.domain.tld
+tcptraceroute hostname.domain.tld 443
+</file>
+This will also illuminate **asymmetrical routing**:
+<file>
+tracepath hostname.domain.tld
+</file>
