[ https://issues.jboss.org/browse/JGRP-2316?page=com.atlassian.jira.plugin.... ] Sebastian Łaskawiec commented on JGRP-2316: ------------------------------------------- [~belaban] This behavior is possible for example with AWS DNS Service. In JGRP-2300, one of the users reported such a behavior, that the DNS Service dynamically remaps the ports. Here's an example DNS SRV response: {code} $ dig jgroups.dev.auth.example.com.svc.cluster.local SRV ; <<>> DiG 9.8.2rc1-RedHat-9.8.2-0.68.rc1.58.amzn1 <<>> jgroups.dev.auth.example.com.svc.cluster.local SRV ;; global options: +cmd ;; Got answer: ;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 16690 ;; flags: qr rd ra; QUERY: 1, ANSWER: 4, AUTHORITY: 0, ADDITIONAL: 0 ;; QUESTION SECTION: ;jgroups.dev.auth.example.com.svc.cluster.local.
