Why I Use a Dynamic DNS Instead of a Static IP Address (and How to Set It Up)
1 min read
Summary
Dynamic DNS (DDNS) employs a domain name which updates to point at the user’s current IP address, meaning that it is not necessary to remember the address permanently and so provides a consistent web address.
This works through automated updates from software on the router or computer which tells the DDNS provider of any IP changes, the DDNS service then updates its records.
Static IP addresses require an upgrade to business internet and can cost up to $50 extra per month, DDNS services are often free.
Security is also increased through DDNS as potential attackers have a harder time targeting a changing IP address and many automated scanning tools cannot cope with the shifting addresses.
DDNS is easier to set up and more flexible as the IP address can change and it is not necessary to stay with the same ISP or plan.
However, certain services do require a static IP address to ensure constant uptime and avoid flags and blocks due to sensitive IP issues.
For those hosting servers or accessing devices remotely, DDNS is often the more convenient and cost-effective option.
