Do not resolve hop addresses Subsequent hop IP addresses are not resolved to mnemonic names.
Use ICMP ECHO instead of UDP datagrams Enforces traceroute to use UDP packets instead of ICMP.
Firewall evasion mode Enforces the same port numbers for UDP and TCP packets. Target port is not incremented with each packet sent.
