Dns not updating records from dhcp

Microsoft specifically recommends to not disable IPv6.

For more information, see IP Addressing in Your VPC. To use your own DNS server, create a new set of DHCP options for your VPC. When you launch an instance into a default VPC, we provide the instance with public and private DNS hostnames that correspond to the public IPv4 and private IPv4 addresses for the instance.When you launch an instance into a nondefault VPC, we provide the instance with a private DNS hostname and we might provide a public DNS hostname, depending on the DNS attributes you specify for the VPC and if your instance has a public IPv4 address.The purpose of DNS is to use easy to remember domain names for websites instead of their numeric IP addresses.

The first name server is the primary server, however if the primary server is not responding then the secondary name server is used to resolve the domain name. Ideally it would be best if you register domain with hosting provider, this way you will not have to deal with transferring domain name or changing name servers.When one link in the chain fails, records may stop getting updated or may even get removed altogether inadvertently!Imagine if an important server's DNS A record suddenly gets changed to the wrong IP. DDNS can sometimes go on a walkabout and it's important to know where to start troubleshooting if this happens.So I have this weird issue on my DHCP server where random computers don't update the DNS records and I have to manually run ipconfig /registerdns on the client computer to force the update.

To make myself understood I'll give you this example: A computer connects to VPN, it gets an IP from another subnet, the DNS is updated accordingly.

As far as disabling IPv6, that has no bearing on registration, unless that's not working either, but then again that depends on the operating system version of the client, DNS and DHCP server.
