Quoting mesaflyguy (Reply 4):
it is physically located in Dulles, Virginia
Quoting simairlinenet (Reply 8):
"Dulles, Virginia" did not exist as an area until well after the airport was built.
What we now call "The Village of Dulles" is an unincorporated area that we used to call "Chantilly." AFAIK, the original "Dulles" community was a housing area developed by the Van Meter real estate group.

Quoting nrt1011 (Reply 8): Now have a go at why us, in Canada, have weird names like YYZ for Toronto etc.
I am missing some of the details, but the short answer is, it goes back to weather reporting station codes. Historically, they were two-letter codes with the first letter chosen from V to Z (I think) to distinguish them from US stations.
When airports were built, they "adopted" the code of the weather station nearby, when one was available, if not they made up a new code. Eventually, someone decided it was necessary to distinguish airports with and without a weather station, and all airports with weather reporting had a Y added to the front of their code (unofficially for "yes weather service is available"), and airports without got a Z instead.
I think it is still true to this day. Smaller Canadian airports without their own weather service have a three-letter code starting with Z, not Y.
Note: strictly from memory and I certainly don't deal with weather station codes every day, so I probably bungled a few things.
