Short answer: yes — if your brand, project, or tech business needs a recognisable international domain and .com is taken, .net is one of the strongest alternatives you can register. At R333.97/year through Allanux Web, it costs roughly the same as a .com and carries decades of trust with browsers, email providers, and search engines.
But "should" depends on what you're building. A local business targeting South African customers is almost always better off starting with a .co.za domain — it's cheaper (R89 to register), signals local presence, and ranks well in local search. A .net shines when your audience is global, your .com equivalent is parked, or you run a technical service (hosting, networking, SaaS) where the extension reinforces your brand.
This guide walks through who benefits most from a .net in South Africa, what it costs, how it compares to .co.za and .com, and when a different TLD is the smarter move.
