"Just" using IATA 3 letter airport codes is not good enough in my opinion because you usally have multiple datacenters/CoLos/PoPs around a bigger airport like MCI or FRA
This.
We use the IATA 3-letter city codes, but then also create a 3-letter abbreviation for the data centre hosting the kit (adding a 1, 2, 3, e.t.c., alongside that since some data centres have multiple facilities in the same city) or building.
Having had devices with txl (Airport Berlin Tegel, now closed, new Airport BER) in their DNS Name and devices in a CoLO in Weismüller Strasse Frankfurt which got first renamed and then sold and again renamed (afaikr) (now fra28)... I think that a convention like <street>.<un-loc>.<tld> is worth to keep in mind. Cheers Thomas
