There are several websites offering good options on dynamic DNS services including the sites found at dnslookup, techrepublic, dnsdynamic, noip, or dyn.
creating an account with a dynamic DNS service
Free DNS services can be obtained through several different companies. OpenDNS is one of the best websites to check for local availability. DNS offers a free trial of their low cost service. DNS Dynamic can be used as a backup when other providers are experiencing heavy traffic volumes.
The dynamic DNS integrated DNS refers to the method of automatically updating a name server in the DNS in real time.
Yes, you can track your IP address by using a dynamic DNS service (the ones I’ve used are free).
One can get a free DNS service by their local internet service provider. Some providers, such as Xfinity, offers these services for free to their consumer if they buy into a specific plan.
Yes it is possible, but most cable Internet providers charge extra for doing so. You want to ask them for a "static IP address". The other option is to use a service that provides Dynamic DNS (Domain Name System). One such provider is TZO.com. This allows you to have a dynamic IP address, and TZO routes the DNS (such as www.mywebaddress.com) to whichever IP address your computer currently has. When your IP address changes a utility (which you install on your system) notifies TZO or whoever your Dynamic DNS provider is.

There is service used to automatically associate names with addresses. DNS that is domain name system is the one that provides that mapping . DNS assigns name to the IP addresses .
An automatic DNS Failover Service is used for to send traffic to a secondary IP address if one's main connection is not working. The DNS Failover Service regularly checks to make sure the main connection is working and if it finds a problem it diverts the traffic.
Some clients that do not support dynamic updates natively include traditional DNS resolvers like dig and nslookup. These tools query DNS information but do not have the capability to update DNS records dynamically. Additionally, some older or simpler DNS client implementations may lack support for dynamic updates.

The "Allow only secure dynamic updates" option may be greyed out if the DNS server is not configured to support Active Directory or if the server is not a Domain Controller. Additionally, if the DNS zone is not set to allow dynamic updates at all, this option will be disabled. To enable it, ensure that the DNS server is integrated with Active Directory and that the zone settings permit dynamic updates.
Traditionally, DNS and DHCP servers have been configured and managed one at a time. Similarly, changing authorization rights for a particular user on a group of devices has meant visiting each one and making configuration changes. DHCP integration with DNS allows the aggregation of these tasks across devices, enabling a company's network services to scale in step with the growth of network users, devices, and policies, while reducing administrative operations and costs.This integration provides practical operational efficiencies that lower total cost of ownership. Creating a DHCP network automatically creates an associated DNS zone, for example, reducing the number of tasks required of network administrators. And integration of DNS and DHCP in the same database instance provides unmatched consistency between service and management views of IP address-centric network services data.Windows Server 2003 DNS supports DHCP by means of the dynamic update of DNS zones. By integrating DHCP and DNS in a DNS deployment, you can provide your network resources with dynamic addressing information stored in DNS. To enable this integration, you can use the Windows Server 2003 DHCP service.The dynamic update standard, specified in RFC 2136: Dynamic Updates in the Domain Name System (DNS UPDATE), automatically updates DNS records. Both Windows Server 2003 and Windows 2000 support dynamic update, and both clients and DHCP servers can send dynamic updates when their IP addresses change.Dynamic update enables a DHCP server to register address (A) and pointer (PTR) resource records on behalf of a DHCP client by using DHCP Client FQDN option 81. Option 81 enables the DHCP client to provide its FQDN to the DHCP server. The DHCP client also provides instructions to the DHCP server describing how to process DNS dynamic updates on behalf of the DHCP client.The DHCP server can dynamically update DNS A and PTR records on behalf of DHCP clients that are not capable of sending option 81 to the DHCP server. You can also configure the DHCP server to discard client A and PTR records when the DHCP client lease is deleted. This reduces the time needed to manage these records manually and provides support for DHCP clients that cannot perform dynamic updates. In addition, dynamic update simplifies the setup of Active Directory by enabling domain controllers to dynamically register SRV resource records.If the DHCP server is configured to perform DNS dynamic updates, it performs one of the following actions:The DHCP server updates resource records at the request of the client. The client requests the DHCP server to update the DNS PTR record on behalf of the client, and the client registers A.The DHCP server updates DNS A and PTR records regardless of whether the client requests this action or not.By itself, dynamic update is not secure because any client can modify DNS records. To secure dynamic updates, you can use the secure dynamic update feature provided in Windows Server 2003. To delete outdated records, you can use the DNS server aging and scavenging feature.
