    Can someone (at Microsoft) tell me how the J# implementation of
    InetAddress.equals(Object) works (Java version of equals)? Does it do a
    byte wise comparison of the address as stated in the Java API (and as it
    does in the Windows JVM) or does it do a simple toString() comparison?

    I have a situation where it seems that it may be doing a String comparison
    instead of an address comparison. This is bad considering that .NET appears
    to do a reverse DNS lookup (also bad) on inbound connections and the reverse
    DNS name may not (usually does not) match the DNS name used in the program.
    This would be especially problematic with dynamic DNS systems.

    I would post some test code, but I can't directly reproduce the problem
    because my test program is doing a reverse DNS on the InetAddress returned
    by InetAddress.getByName("..."). However, I have a program up and running
    which displays the reverse DNS for one outbound connection but not for
    another yet both used the same InetAddress.getByName("") method. I don't
    understand why that would happen, either.

    This is seen on .NET and J# 1.1.4322
