Any idea why it doesn't give a HostMin/HostMax/Hosts field when passing an IPv6 range? $ ipcalc 2600:1ff2:4000::/40 Address: 2600:1ff2:4000::

  "HostMin" = Prefix. "HostMax" = Prefix followed by all f's. "Hosts" = some ungodly large number (i.e. "small" for this is 2^64) you typically don't care about anymore. If someone did something atypical like use a /123 (mask >64, mask not a multiple of 4) and you do actually want to see host max and host count as a result you can pass "--all-info". Otherwise a combination of the ridiculous size and hex encoding makes everything but "what is the prefix and netmask" irrelevant.

  shameless plug, I made an ipcalc6 in rust that does it (with colors) https://github.com/ba9f11ecc3497d9993b933fdc2bd61e5/ipcalc6 https://github.com/ba9f11ecc3497d9993b933fdc2bd61e5/ipcalc6 user@box:~/Documents/code/rust/ipcalc6$ cargo run 2600:1ff2:4000::/40 Finished dev [unoptimized + debuginfo] target(s) in 0.01s Running `target/debug/ipcalc6 '2600:1ff2:4000::/40'` WARNING : netmask /40 is smaller than /48, this is unusual if ip of type : Global Unicast Address and Link-Local Address Type: Unicast Global Address: 2600:1ff2:4000:0000:0000:0000:0000:0000 NetMask: 40 Hosts/Net: 19342813113834066795298816 Address: 0010011000000000.0001111111110010.0100000000000000.0000000000000000.0000000000000000.0000000000000000.0000000000000000.0000000000000000 NetMask: 1111111111111111.1111111111111111.1111111111111111.0000000000000000.0000000000000000.0000000000000000.0000000000000000.0000000000000000 HostMin: 0010011000000000.0001111111110010.0100000000000000.0000000000000000.0000000000000000.0000000000000000.0000000000000000.0000000000000000 HostMax: 0010011000000000.0001111111110010.0100000000000000.1111111111111111.1111111111111111.1111111111111111.1111111111111111.1111111111111111
