The location dl.fedoraproject.org is at is currently only ipv6. This is not a bug which can be fixed by the project.
He means ipv4 only. ;) You can use: download-cc-rdu01.fedoraproject.org or download-ib01.fedoraproject.org which both have ipv6. Or your local mirror (mirrors.fedoraproject.org/publiclist) There are plans to bring up ipv6 in our datacenter, but we largely have no control over it. :(
In our datacentre, IPv4 addresses are super expensive, largely in the form of punishing setup fees: https://docs.hetzner.com/general/others/ipv4-pricing/ This is caused by the ever skyward prices of IPv4 addresses, which are creating a bigger bubble than bitcoin: https://auctions.ipv4.global Please be aware when declaring "not a bug" that lack of support for IPv6 is costing a lot of people a lot of money.
It is more of a 'not a bug we can fix' and should have been closed 'CANTFIX'. It is also not a software bug which the bugzilla system is meant to track. It is more of a systems problem which needs to be tracked in https://pagure.io/epel/ where the volunteers who work on EPEL can fix the documentation to point out that for ipv6 you go to https://download-ib01.fedoraproject.org/pub/epel/
I have filed https://pagure.io/epel/issue/183 for you. I am now going on a couple weeks of family leave so hopefully that will get fixed for you.
I know this ticket is closed. But I'm not sure that the affected people are watching the epel issue. So here is our first attempt at fixing the documentation. Please let us know if it helps.
