If you don’t need to use an account, I’d recommend browsing on libreddit or teddit – both proxy your traffic through their servers.

Aside from that, te easiest way would probably be to use Tor, a VPN, or some other proxy; your internet service provider owns one or more blocks of IP addresses, but I don’t know how often they change addresses for the individual customers. Tor Browser is the easiest and most secure way I know of, but you may need to occasionally refresh your identity in case Reddit has blacklisted some of the endpoints.
