> All of (...) 17.0/8... are unrouted?

Definitely not complete:

    apple.com.              1424    IN      A       17.172.224.47
    apple.com.              1424    IN      A       17.178.96.59
    apple.com.              1424    IN      A       17.142.160.59

Most of these are routed and in very active use. I have suballocations of large chunks from 12/8 and 38/8. People will be unhappy if you picked most of them.

73/8 is entirely owned by Comcast and used for customers. 44 is no longer a /8, but sold+split and half in active use by AWS.
