A DESCRIPTION OF THE PROBLEM :
The most significant difference between IPv4 and IPv6 is the address size, which is only 32 bits in IPv4, but 128 bits in IPv6. See the section IPv4 and IPv6 incompatibility in The Java Tutorials for more information.

There is a small typo in this sentence : "which is only 32 bits in IPv6, but 128 bits in IPv6." it should be IPv4 in the first part.
