Blocking doesn’t really help with DDOS, since the traffic is still hitting the server and from the standpoint of the VPS provider it doesn’t look much different.
Some VPS providers offer DDOS protection as an addon, but just moving to a different provider might solve it. If you’re just hosting stuff for friends/family it doesn’t seem like there would be much reason to DDOS your IP, unless the IP was recycled from something before that people are still attacking.
