I don't see this service listed in the "Legitimate uses of fast flux"

again, this comes back to an excellent point hit very well yesterday: thee
low TTL check is ONE characteristics of fast flux, not a single indicator.
one of many criteria that we use to screen for fast flux service networks
and their associated domain names.
in addition, dDNS-for-home-users has 1 IP per A record, usually, that's
usually stable at TTL+1.
again, this isn't an issue that needs to be addressed because the low TTL
is just one common feature of FFSNs.
