> The mix of ip-address and hostnames may cause confusion and problems.
> One example is that the EndPoint is internally represented as a four byte
> IPv4 address in the gossip messages, but upon arrival there is a
> reverse-lookup into a hostname that is used to create the new EndPoint java
> object on the receiver side. This is likely to cause problems if a fully
> qualified hostname is used on one end but the reverse lookup returns just a
> short machine name, or vice versa.
> It also has the strange effect that if you configure ListenAddress using
> IP-addresses it works only if it is NOT possible to do a reverse lookup of
> those addresses.
> Suggest FBUtilities.getHostName() is renamed to getHostAddress() and made to
> always return the string representation of the IPv4 address.
> Additionally EndPoint.fromBytes() should not attempt a reverse lookup, but
> just convert the four byte wire format of the IP to the string representation.
