Is it 255?
0
answer given is 509

255(going forward) + 254(icmp coming back)
0
If we consider only one way then ,

Max value of TTL will be 255 hence it can take max 255 hops to reach destination ==> in between it can travel 254 routers right ??

It didn't reach destination that's why ICMP error came. So the router at which TTL becomes 0 will also be counted.
