[afripv6-discuss] IPv6 rollout…

[maina.noah at ipv6.or.tz]

Andrew,

Great work and we the afro netizens are excited to see more v6 adoption
going on in the continent. I will also be happy to share some exciting
succes stories from an ISP point of view for one of the operators in
Tanzania who are now dual-stack and all network nodes and servers running
both v4 and v6 and even selling v6 termination and Transit to downstream
customers.

Cheers,

./noah
