That will not help because select has a hard coded limit of the number of bits in its read, write and error sets.
What could help us to open c-ares socket very early in the program to get a low FD number. Or switch to poll. I posted a half done, good enough for me poll fix to this list some years ago. Or use one of the other APIs to get the socket descriptors and poll.
