There is something hosting a blank page, and you could easily just drop in an HTML page that redirects here if indeed it's being hosted and you have access to it. Doing it via DNS is better, but you cannot normally have a CNAME on an apex domain, so it's a little trickier, but doable as some providers have some clever custom solutions. The way I would personally do this is setup cloudflare (you can use the free plan for this use-case) - and use their CNAME flattening so pelletville.com ends up here. All the work is done for pelletville.com, and nothing changes for pelletfan.com (it's transparent). I do something very similar for my own site, which is hosted via github pages but uses my own domain name.
