# Native IPv6 is supported, however you must escape the colon in the IPv6 Address # Also be sure to comment out JVM_OPTS="$JVM_OPTS -Djava.net.preferIPv4Stack=true" # in cassandra-env.sh fe80\:0\:0\:0\:202\:b3ff\:fe1e\:8329=DC1:RAC3 Maybe you have to escape the IPV6 addresses in the cassandra.yaml in the same way. I think it’s worth a try. -Razi On 4/12/17, 3:08 PM, "Martijn Pieters" <mjpiet...@fb.com> wrote: From: sai krishnam raju potturi <pskraj...@gmail.com> > We have included the IPV6 address with scope GLOBAL, and not IPV6 with SCOPE LINK in the YAML and TOPOLOGY files. > > inet6 addr: 2001: *** : ** : ** : * : * : **** : **** Scope:Global > inet6 addr: fe80 :: *** : **** : **** : **** Scope:Link > > Not sure if this might be of relevance to the issue you are facing.
