What this means
Anyone can open an inbox at 2iij.net, so an address there says nothing about the company the person works for. That makes it a personal email, even when someone uses it for work. It is on our free email providers list.

Questions about 2iij.net
Is 2iij.net a business email?
No. 2iij.net is a shared email provider, so isBusinessEmail classifies it as "personal". A business email uses a domain the company owns.
Is 2iij.net a free email provider?
Yes. 2iij.net hands out inboxes on its own domain to individuals, which is what makes an address there a personal email.
Should a B2B product accept 2iij.net sign-ups?
It depends on what you need. If you need a company tenant or a company to sell to, ask for a work email; if you only want real people, accept it. The b2b policy blocks personal addresses and the lenient policy allows them.
How can I tell 2iij.net apart from a company domain in code?
POST the address to /v1/check: shared providers come back with category "personal" and is_free_provider: true, company domains with category "business".
