What is rlTunnelIsatapDnsHostName?

This read-write DnsName sets the domain name the device uses to discover its ISATAP tunnel router. An admin configures this to point at the site's actual ISATAP-resolvable hostname (conventionally something like isatap.example.com) so the device can locate the correct router via DNS. For example, setting this to isatap.corp.example.com lets the device resolve that name to find the ISATAP router address for the corporate network.
