+Network Health Checker - Hálózati diagnosztikai eszközök.
+
+Ez a modul tartalmazza a hálózati monitorozáshoz szükséges eszközöket:
+- Ping monitor (ICMP)
+- Port scanner (TCP)
+- DNS lookup
+- Subnet calculator
+- SNMP query
+- Network info
+
+Használat:
+    >>> from network_health_checker import ping_host
+    >>> result = ping_host("8.8.8.8")
+    >>> print(f"Status: {result.status}, Latency: {result.latency_ms}ms")
+
+CLI használat:
+    $ python -m network_health_checker ping 8.8.8.8
+    $ python -m network_health_checker scan 192.168.1.1 -p 22,80,443
+    $ python -m network_health_checker dns google.com -t MX
