ARM/CRM/PU:
Recommendation: Wait for stage 4.

launch_process->consoleIP:
References in only three projects: CompSupport, RACommon, and TPTPClientCompTL. None of these projects use the value, they only translate it, read it from a buffer, or write it to a buffer. I tested this by overwriting the value in the AC and profiling from a remote machine, and it works as expected.
Recommendation: Value is not used, no change required.

start_monitor_remote->ip:
hcjbnd.c:
- The only places where start_monitor_remote->ip is used is under RA_START_MONITORING_AGENT_REMOTE code, which isn't  used with the new AC.
- The only other references to start_monitor_remote are fields unrelated to IPv6. No rewrites required.

JvmpiWriter.c:
- Both references are RA_START_MONITORING_AGENT_REMOTE only.

hcthread.c:
- RA_START_MONITORING_AGENT_REMOTE only.

RACSupport.c (CompSupport):
- Reading from buffer, writing to buffer, and translation, only. No functional use here.

RAComm.c (RACommon):
- Reading from buffer, writing to buffer, and translation, only. No functional use here.

TPTPClientCompTL:
- IP address fields not used, no rewrite required.

Recommendation: No rewrites required.
