ttl Parameter (IPv4)

Description

Controls the time to live (TTL) value in the IPv4 header for the outbound IPv4 ICMP error and reply packets. The TTL defines the maximum number of routers a packet can pass through on the path to the destination. It is primarily used to clear messages from the network when a misconfiguration would otherwise cause messages to endlessly loop through the same set of routers.

The ttl set on outbound ICMP requests and on UDP, TCP, and SCTP messages is not controlled by this property. It is instead controlled by the _ipv4_ttl Parameter property for each respective protocol.
