Ok, couple of things to add here:
It sounds like you are dealing with the older BEA WebLogic JsessionID cookies that have the following format:
! ! !
In a clustered environment that have the following additional fields
! ! ! !
In this case, the is actually the integer representation of the IPv4 address in little endian format. So, to make sense of that number you may want to look at some of the tricks we did for Window Terminal Servers which use the same type of host representation: Click here

I will point out that this format is only functional in IPv4 and hence I believe both Microsoft and BEA have stopped utilizing this approach in their newer versions. So, our current implementation of WebLogic persistence uses only the JVMID for persistence (which you've already seen included above).
I have not seen the newer format first hand, so I'm not sure if they've simply switched to putting the host name in the header instead of the address as a number. If so, the above mentioned approach may work.
