IP addresses might vary depending on geo location or time. Here is what I get from DNS currently, that you can put in your /etc/hosts

51.38.69.52 archive.is archive.today

41.77.143.21 archive.ph archive.li archive.vn archive.fo archive.md

And if all else fails, install Tor and access their site at archiveiya74codqgiixo33q62qlrqtkgmcitqx5u2oeqnmn5bpcbiyd.onion
