ExtendSim 2024 and 10 software packages support IPv6.
The only time ExtendSim reaches out over the internet, is for activation of the software. ExtendSim and the ExtendSim License Manager use the Reprise License Manager (RLM) version 12.3BL3, platform x64_w4 for activation. Beginning with RLM v11.0, RLM began supporting IPv6 on Windows.
