LMOS 7.2.48.2 was submitted to the University of New Hampshire InterOperability Testing Laboratory and successfully passed testing for IPv6 and DHCPv6 certification under the USGv6 program, a U.S. Government program for certifying that a tested device can interoperate according to relevant standards with other devices in an IPv6 network. Final certification was obtained in September 2020.

All versions of LMOS above 7.2.48.2 are also similarly certified, since they use the same certified IPv6 stack. For a full test report, please see the UNH Testing Registry for a full test report.
