What is the correct tag for the netbsd-1-6 branch?

#frog env | grep CVSROOT
CVSROOT=:pserver:anoncvs@anoncvs.netbsd.org:/cvsroot
frog# pwd
/usr
frog# cvs login
(Logging in to anoncvs@anoncvs.netbsd.org)
CVS password: 
frog# cvs update -d -P -rnetbsd-1-6 src
cvs [server aborted]: no such tag netbsd-1-6
anoncvs.netbsd.org: Connection refused
cvs [update aborted]: end of file from server (consult above messages if any)
