But those ARE two different instances.  The interesting thing is that
the class in both cases seems to be anonymous.

How did you build hosts?  You say that it contains different "class instances"

One way to get such anonymous classes would be something like this:

irb(main):040:0> fd = Foo.dup
=> #<Class:0xb7d1404c>
irb(main):041:0> fd.new
=> #<#<Class:0xb7d1404c>:0xb7d11310>
irb(main):042:0> fd.new
=> #<#<Class:0xb7d1404c>:0xb7d0f074>
irb(main):043:0> fd.new.equal?(fd.new)
=> false

Note that the two instances have the same oid for their class, (which
is the copy of the Foo class), but different oids of their own.
