> After update from F12 to F13.1 the ping behavior has changed, because it's now requires -4/-6 option to resolve names:

> ping ya.ru
> ping: UDP connect: No route to host

The problem is that ya.ru has both IPv4 and IPv6 addresses, ping is defaulting
to IPv6, and the host on which the command was run has IPv6 configured but
cannot route to ya.ru.  ping -4 ya.ru should work.  ping, like many other
utilities, now supports both IPv6 and IPv4, along with -4 and -6 options. 
Perhaps your script should use ping -4.  btw, ping6 is just ping -6.
