method Socket.prototype.setTTL
Usage in Deno
import { Socket } from "node:dgram";
Socket.prototype.setTTL(ttl: number): number
Sets the IP_TTL socket option. While TTL generally stands for "Time to Live",
in this context it specifies the number of IP hops that a packet is allowed to
travel through. Each router or gateway that forwards a packet decrements the
TTL. If the TTL is decremented to 0 by a router, it will not be forwarded.
Changing TTL values is typically done for network probes or when multicasting.
The ttl argument may be between 1 and 255. The default on most systems
is 64.
This method throws EBADF if called on an unbound socket.
