Which part of NIS?  There's a new upstream for libnsl
<https://github.com/thkukuk/libnsl> and the NSS module
<https://github.com/thkukuk/libnss_nis>.  (There is a nisplus module
as well.)

All these use libtirpc and support IPv6 in addition to IPv4.  As far
as I know, it is possible to build a full NIS stack without relying on
any of the legacy glibc code.

(I don't know about nfswatch.)
