TM has announced that it will start migrating some customers from public IPs to private IPs for added security.
If you are an Unifi Broadband customer that relies on public IPv4 IPs, you may find yourself affected soon as you will be shifted to private IP.
The network provider is said to be implementing Carrier-Grade NAT (CGNAT) for security purposes so that bad actors won’t be able to identify public IPv4 addresses assigned to customers.
This is also a way for TM to deal with the issue of IPv4 address exhaustion.
The implementation will only be done for Unifi 30Mbps, 50Mbps, and 100Mbps customers and customers who subscribed to higher speed plans are not affected.
Meanwhile, the migration is said to only affect customers with a dynamic IP so individuals and businesses with a static IP address will not be affected too.
According to the FAQ, the migration exercise will be implemented in stages from mid-September 2021 to January 2020 between 2 a.m. to 4 a.m. Affected customers may experience a short downtime of 2-5 minutes.
TM has also listed some of the services that may be affected, including non-cloud-based CCTVs, server hosting services, and online multiplayer games hosted by the customer.
For those who have a file-sharing service, FTP or NAS that uses a public IP, it will be affected as well.
Meanwhile, if you are worried about whether you need to reconfigure the IP to access your devices, TM advises customers to check with the device manufacturer for further clarifications.
