man ufw doesn't seem to have much to say on the matter, but
https://help.ubuntu.com/community/UFW
suggests "any" in this context means any destination IP address (given
that there may be many associated with a host):
> *Allow by specific port, IP address and protocol*
> 
> sudo ufw allow from <target> to <destination> port <port number> proto
> <protocol name>> 
> *example: allow IP address 192.168.0.4 access to port 22 using TCP**
*> 
> sudo ufw allow from 192.168.0.4 to any port 22 proto tcp
