About this network

Posix Systems (Pty) Ltd is a small South African internet company, registered with AFRINIC and long associated with Mark Elkins, a fixture of the South African internet and DNS community.

What it's used for

• Hosting, DNS and connectivity services for a modest South African customer base.
• It announces roughly a dozen prefixes, effectively all of them inside a 192.96.24.0/21 registered to the company, plus an IPv6 /32.

Notable

• A hosting/service-provider network at boutique scale — a few thousand addresses in total, run by a small independent operator rather than a national carrier.
• The address space is AFRINIC-registered and South African (ZA), so despite the low AS number this is an African, not a North American, network today.

Interesting

• Posix Systems' proprietor has been active in ZA internet governance for decades, and the company's long-running presence in AFRINIC's registry reflects that continuity rather than a large network.
