<= I (mistakenly?) thought this was *the* problem
3. Whether the problem is ICMP (the "ping") or DNS (a hang trying to resolve the name you're trying to "ping" to).
The problem could definitely be DNS even if you're ping'ing a raw IP address.
4. Who knows - the problem might even be something weirdly off-base like SeLinux or IPV6.
SUGGESTIONS:
1. Try ping with a timeout (e.g. "-w SEC") and see if it behaves differently
2. Try a bogus address and see if it behaves differently
3. "Pull the plug", try pinging a local machine (with the network cable unplugged) and see if it behaves differently
PS:
Is "Wolverine" an hommage to the Stan Lee/"X Men" character, the 1980's John Milius movie "Red Dawn", or something else altogether?

1.) With a timeout: no change.
foo@bar:~$ ping -t 100 4.2.2.2

2.) No difference when pinging a bogus address

3.) Same thing when pulling the plug
foo@bar:~$ ping 10.10.10.1
PING 10.10.10.1 (10.10.10.1) 56(84) bytes of data.

-----P.S. - I think you're the first person ever to get the Red Dawn reference. However, I had to spell it with an "e" instead of an "i" because someone already had "wolverine", so everyone thinks it's misspelled.
