Description of problem: It seems that the package glibc-2.2.93-5.i386.rpm shipped with redhat-8.0, has no ipv6 support. Looking at strace result on lines 121-131 it simply tries to do a ipv4 query to the default nameserver (resolv.conf has only an ipv6 only server). Version-Release number of selected component (if applicable): 2.2.93-5 How reproducible: Always Steps to Reproduce: 1.ping6 www.kame.net (e.g) 2. 3. Actual results: Expected results: Additional info:

There is no way to compile glibc without IPv6 so this is definitely not the reason. From your strace output it seems there is a problem with the DNS server. Reading the results produces problems. Anyway, I assume ping6 uses getaddrinfo. getaddrinfo has been changed significantly for RHL9. Please try RHL9 and let us know.
