This paper presents comprehensive operational insights from deploying IPv6 across six commercial ISP
backbone networks in sub-Saharan Africa, collectively serving more than 44.8 million subscribers. Over an
18-month period, we conducted systematic measurements to evaluate real-world performance and
deployment challenges under dual-stack operation. Our analysis covers throughput, latency, packet loss,
and routing convergence across diverse backbone and access environments. Results show that IPv6
delivers performance comparable to IPv4, with a modest 4–6 percent TCP throughput reduction and slight
UDP gains at high bitrates. Beyond performance, we identify key operational barriers including CPE
compatibility gaps, DNS and DNSSEC integration issues, and network management upgrades. We provide
actionable recommendations for IPv6 planning, capacity engineering, and transition strategy selection,
demonstrating that IPv6 deployment at ISP scale is both feasible and sustainable.
