Yeah, have to update my local DNS routes. I had .dev pointed to 127.0.0.1

This has been the topic of HN for the past few days for anything .dev.

You should be using .test or .localhost for any development domains: https://tools.ietf.org/html/rfc2606#section-2

I did this years ago. Developers have been using .dev for decades, these TLDs are pretty new.

.corp, .home, and .lan are also reserved, just not codified into an RFC yet.

They aren't reserved as the term is usually used for domains. Reservations don't exist in outside of those codified in RFCs; the IANA is the party that reserves domains and the full current list of reserved special use domains is here:

https://www.iana.org/assignments/special-use-domain-names/sp...

More general info on reserved domains is here:

https://www.iana.org/domains/reserved

Note that of those domains you falsely describe as reserved, .home was suggested as a special use domain in RFC 7788, but that was updated by RFC 8375 to the reserved domain .home.arpa.

.home, .corp, and .mail (but not .lan, AFAICT) are subject to a ICANN policy decision against granting delegations as TLDs, though, which means they won't become real TLDs while that policy is in effect (it doesn't mean they won't get reserved for a use which might conflict with what you might adopt them for, the way .local has for some uses, though.)

Until someone buys test.

Will a boycott .dev site movement take hold?

ICANN will never delegate .test. It's reserved per the linked RFC.
