Dumb rationale they gave you, but numeric is the way to go if its static.
Last week my "internet went down". Yet when I checked my site status from my phone, everything was updated and current. I gave up trouble shooting after a while, and decided it was the ISP's DNS messing up. Put the laptop down and did "other stuff"
It turns out it was every customer of my ISP, which is about half my province. 3 or 4 hours.
And I was correct about the DNS being the culprit although they never publicly acknowledged.
So my fling and WD were unaffected because they were numeric, and chugged right through.

ps: some of the rants the following day, or via mobiles were funny. Come on its not the end of the world. The ones that were really funny, were ones like " I actually played a game with my kids... watched a family movie". And of course the "9 months from now there will be an mini baby boom"
Thanks I got it! What a pain in the rear!
