If this was done in a distributed way, almost like DNS, where anyone could get it from anyone else, there would simply be too many systems running it to make it possible to kill it via DDOS.

A textfile containing only IP-Addresses can by zipped down to around 1/3
of his size.
A file containing 200 Ips has an original size of 3,1 kB
The zipped file has 1,1 kB
(Probably the zip algoritmus will work bether for larger files because
there are more equal 3-digit-strings.)
Multiplicating it by 100.000 assuming a blacklist containing 20 million
"bad" IPs would create a 110 MB file.
But this 20 million IP's are a initial value. I have no exact idea but I
assume there should be something between 1000 and 10000 new/removed IPs
per day.
If my theory has no errors we can expect daily updates between 0,5 and
5,5 MB.
That shouldn't be a problem.
