Why does any company needs more than one 2nd level domain?
Microsoft, I'm looking at you (https://learn.microsoft.com/en-us/microsoft-365/enterprise/urls-and-ip-address-ranges?view=o365-worldwide https://learn.microsoft.com/en-us/microsoft-365/enterprise/u...). It nerve-wrecking trying to figure out if some login box or link is legit. They claim to be transitioning to cloud.microsoft, but if you go there, you are redirected to yet another new domain (microsoft365.com) which looks like a scam site, which doesn't render properly in Firefox.
Why do we allow this?
- jiggawatts 3y agoDomains used for bulk outbound email are typically separated from the normal corporate email domain to prevent employee emails getting blocked at customer mail gateways by anti-spam heuristics. Practically every large org gets burnt by this once, learns their lesson, and then splits their domains. Microsoft has something like a hundred domains, including purposefully misspelled ones like "microsft.com", which is real, owned by them, and regularly used to bypass "security filtering" by paranoid admins.

- cj 3y ago> Why does any company needs more than one 2nd level domain? Re: the first part of your comment, the most common reason I've seen is companies using 2nd domains to send emails that are at higher risk of bouncing or being marked spam (newsletters, cold outreach, etc). And using your primary domain to send "more important" emails from.
