Alter IP address of SQL Server AlwaysOn Failover clustering Iistener

Question

Hi,
Is there a possibility to change the IP address of SQL Server AlwaysOn Failover clustering Listener IP address without deleting the exiting one and also retaining the same DNS name.
NOTE: Only the IP address needs to be altered rest all (DNS, port) should remain the same.
Regards

Hi Karthikkk,
As your description, you want to modify the listener IP address in AlwaysOn availability group without changing other settings including DNS and port. To achieve this, you could modify a listener IP address on primary replica using the following statement:
ALTER AVAILABILITY GROUP group_name
MODIFY LISTENER ‘dns_name’
ADD IP { (‘four_part_ipv4_address’,  ‘four_part_ipv4_mask’) | (‘dns_nameipv6_address’) }
