Strange behavior when host is down.

RouterOS General
1

I noticed something strange, what isn’t a real problem for me. I bumped into it when using a python script to check hosts that trips over this issue.
When I ping for a host that is none existing in the network but has an IP in the own network, once in a while the router returns network unreachable:
SEQ HOST SIZE TTL TIME STATUS
40 192.168.88.15 timeout
41 192.168.88.15 timeout
42 192.168.88.76 84 64 990ms host unreachable
43 192.168.88.15 timeout
44 192.168.88.15 timeout
45 192.168.88.76 84 64 988ms host unreachable
46 192.168.88.15 timeout
47 192.168.88.15 timeout
48 192.168.88.15 timeout
49 192.168.88.15 timeout
50 192.168.88.15 timeout

192.168.88.15 is the non existing host
192.168.88.76 is the router.
Running 6.46.6

Does anyone know how to fix this?

I don’t have this behavior.
