RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Not able to add Reverse zone IP in DNS

Via CLI :

[root@rhel7ad ~]# ipa dnszone-add 222.65.10.in-addr.arpa.
Authoritative nameserver: rhel7ad.testrelm.com.
Administrator e-mail address [hostmaster.222.65.10.in-addr.arpa.]: 
  Zone name: 222.65.10.in-addr.arpa.
  Authoritative nameserver: rhel7ad.testrelm.com.
  Administrator e-mail address: hostmaster.222.65.10.in-addr.arpa.
  SOA serial: 1389297743
  SOA refresh: 3600
  SOA retry: 900
  SOA expire: 1209600
  SOA minimum: 3600
  BIND update policy: grant TESTRELM.COM krb5-subdomain 222.65.10.in-addr.arpa. PTR;
  Active zone: TRUE
  Dynamic update: FALSE
  Allow query: any;
  Allow transfer: none;

[root@rhel7ad ~]# rpm -qa ipa-server
ipa-server-3.3.3-8.el7.x86_64

Web UI is right, 222.65.10.in-addr.arpa. is not a valid *IP network address*.

Try 10.65.222.0/24 or checking "Zone name" via the radio button.

Thanks,10.65.222.0/24 is works.
So this is not a bug.

Closing.
