If you do a reverse lookup on that IP to see what domains were/are hosted there you will come up with 162,685 results. It is not uncommon in a shared hosting environment for domains to use the same address. The service is probably designed that way, so it could just be a coincidence there. The owner of the IP is shopify.com that looks like an ecommerce service. It could also be possible that both sites were hosted on the same service and the service had a mixup in their DNS or database etc. So who knows, maybe something shady is going on sharing addresses or maybe it was just a mistake.
