Fping false response

[jocms]

Any host I register on Zabbix return "is alive":

bash-4.3# fping 10.42.0.31
10.42.0.31 is alive
bash-4.3# fping 10.42.0.32
10.42.0.32 is alive
bash-4.3# fping 10.42.0.33
10.42.0.33 is alive
bash-4.3# fping 10.10.10.10
10.10.10.10 is alive
bash-4.3# fping 1.2.0.9
1.2.0.9 is alive

Looks strange. Is this true only for hosts which defined in Zabbix web frontend? What is output of the ip route and ip address. What default ping is return? ping 10.10.10.10 -c 5 -q
