Verify the target host 10.0.0.5 is reachable using ping.

$ ping 10.0.0.5

NETWORK RECON TOOLKIT

The Mission

Network reconnaissance is fundamental to security operations. Map active hosts, identify open connections, and understand network topology.

ping - Test Connectivity

$ ping 10.0.0.5
Send ICMP echo requests
$ ping -c 4 host
Send only 4 packets

netstat - Network Statistics

$ netstat -tuln
Show listening TCP/UDP ports
$ netstat -an
All connections, numeric

ss - Socket Statistics

$ ss -tuln
Modern replacement for netstat
$ ss -tp
Show process using socket

ip - Network Configuration

$ ip addr
Show IP addresses
$ ip route
Show routing table
PRO TIP:

ss is faster than netstat on systems with many connections. Use ss -tuln for quick port scans.
