Public bug reported: GNU Wget 1.17.1 built on linux-gnu. (Ubuntu 16.04 amd64)
IPv6 local link addresses (fe80::/10) are tricky. Network interface has to be specified to tell OS what interface to use. wget cannot handle that First, IPv6 address, no interface specified, it fails with an error (error comes from OS) user@test:~$ wget http://[fe80::87f4:81fa:b481:d781]/test.html --2018-06-08 17:29:08-- http://[fe80::87f4:81fa:b481:d781]/test.html Connecting to [fe80::87f4:81fa:b481:d781]:80... failed: Invalid argument. Second, IPv6 address with interface specified (%enp4s0 added to IPv6 address), wget cannot handle this address format (and this bug report is about this case) user@test:~$ wget http://[fe80::87f4:81fa:b481:d781%enp4s0]/test.html http://[fe80::87f4:81fa:b481:d781%enp4s0]/test.html: Invalid IPv6 numeric address.
