4.3.2 "Dynamic DNS" submenu. Dynamic DNS Configuration
Dynamic DNS (domain name system) allows information to be updated on DNS server in real time and
(optionally) automatically. It is applied for assignment of a constant domain name to a device (computer,
router, e.g.NTP-RG) having a dynamic IP address. The IP address can be assigned by IPCP in PPP
connections or in DHCP.
Dynamic DNS is often used in local networks where clients get IP addresses by DHCP and then register their
names in a local DNS server.
