The upstream webpage says that this package is obsolete and recommends two alternatives that are both available in Gentoo (ncat, which is part of nmap and openbsd-netcat): http://deepspace6.net/projects/netcat6.html Given that upstream recommends not to use that package it might be reasonable to remove it from Gentoo.
Note that some packages, like libvirt-3.0.0, have net-analyzer/netcat6 explicitly as RDEPENDs. Whether that is actually a correct RDEPEND I don't yet know. (I certainly prefer to have a choice of netcats...)

DESCRIPTION="netcat clone with better IPv6 support, improved code, etc..." This description suggests this clone is newer/better/improved/hot. This is misleading and creates a hard time when choosing between the possible netcat variants. Besides that, its behaviour is quite different compared to RHEL/Ubuntu nmap-ncat/netcat-openbsd versions. After years, I found this package is actually obsolete, so please get rid of it. If we really need to keep this obsolete software in portage, can you at least change the description to something like: DESCRIPTION="obsolete netcat clone ..."

Unless I'm mistaken, all revdeps support some other implementation (in || dep).

As others have mentioned there exist dependencies on this package. I have libvirt stable version 4.9.0 installed and it depend on: || ( >=net-analyzer/netcat6-1.0-r2 >=net-analyzer/openbsd-netcat-1.105-r1 ) So you can use openbsd-netcat instead. However, there do not exist any version of openbsd-netcat which has been marked stable. So right now, stable libvirt depends on unstable openbsd-netcat or masked netcat6. As I am no expert in netcat versions, I just mention it here, thought it might belong to a libvirt or openbsd-netcat bug report.
I see the issue now, I'll either fix it or revert the last rites ASAP.
@Michał Górny That would be nice, just got a blocker because of the masked and situation Jesper just described.

This means you've selected netcat6 explicitly. $ emerge --deselect netcat6 should solve it.
THANK YOU for noting suggested replacements in the masking message. Where should such praise best be directed in future?

Guess it is time for a virtual/netcat (provided that they are drop-in replacements)?
(In reply to Matthias Maier from comment #13) > Guess it is time for a virtual/netcat (provided that they are drop-in > replacements)? Most are not drop in replacements.

Dropped all netcat6 dependencies from app-emulation/libvirt, also see bug #672992
see https://wiki.gentoo.org/wiki/IPv6_router_guide netcat6 should be removed here too.

Just a note: netcat6 has the "--exec --continuous" mode where it can handle multiple incoming connections; neither net-analyzer/netcat nor net-analyzer/openbsd-netcat have this functionality, so netcat6 will be missed. Now, ncat, which is installed by net-analyzer/nmap[ncat], has this functionality, but net-analyzer/nmap is a much larger package, and it's difficult to remember that I need to install nmap[ncat] if all I want is just netcat.
