DigitalOcean Reserved IPs

Consider alternatives when:

1. Email deliverability and rDNS/PTR requirements are critical: Reserved IPs do not support PTR/rDNS, and community discussions identify reputation and blacklist concerns for cloud IP ranges.
2. Static IPs are required for managed platforms other than Droplets: App Platform and other managed services use different networking semantics.
3. Multiple public IPs per server are required: DigitalOcean limits a Droplet to one Reserved IP/BYOIP at a time; some providers support additional IPs per server.
4. A higher default quota for static IPs is needed: The default limit of three Reserved IPs per account may be restrictive for multi-environment setups.
5. Load balancer level stable ingress is the preferred abstraction: In some architectures, a load balancer provides a better model than instance-level IP reassignment.

Documented distinguishing features:

• Cost profile when attached: Reserved IPv4 is not charged while assigned to a Droplet, which reduces the incremental line-item cost for always-attached IPs.
• Simpler operational model for basic HA patterns: Documentation and community examples show reassignment as a straightforward failover mechanism.
• IPv6 Reserved IP availability: IPv6 Reserved IPs are generally available and remain free when unassigned.

Where competitors provide different trade-offs:

• Lower idle IP costs (Vultr, Hetzner) may be preferable when maintaining pools of unassigned IPv4 addresses.
• Providers that support multiple IPs per server (such as Hetzner) offer additional architectural flexibility.

G2 (platform-level): Some reviewers describe the UI as simple and note that documentation and tutorials are helpful. Other reviewers report occasional dashboard performance issues and note limitations in advanced networking controls.

TrustRadius (platform-level): Commonly noted strengths include developer-oriented tooling, accessible APIs, and comprehensive documentation.

PeerSpot (platform-level): PeerSpot reports DigitalOcean mindshare in IaaS as a low single-digit engagement-based metric in recent reporting; the metric is engagement-based and should be treated as directional rather than an exact market share figure.

DigitalOcean Community Q&A: Questions frequently ask whether Droplet IPs change; community answers emphasize that a Droplet’s public IP remains static as long as the Droplet exists, and that Reserved IPs are useful when reassignment or migration is required.

Reddit discussions: Community posts describe Reserved IP assignment behavior (for example, how a Reserved IP may appear as the primary public IP for inbound traffic) and raise concerns about IP block reputation and blacklisting. These reputation concerns affect the utility of static IPs for email and other reputation-sensitive workloads.

DigitalOcean Reserved IPs are static, publicly accessible IP addresses (IPv4 and IPv6) that can be assigned, unassigned, and remapped between Droplets within the same datacenter. The primary functional purpose is to provide operational continuity (stable endpoints) and a simple failover pattern without changing DNS records. Official documentation describes the feature as supporting automated failover and high availability by remapping the IP between Droplets.

Key capabilities (as documented):

• Static public IP (IPv4 and IPv6) that can be assigned/unassigned and remapped between Droplets in the same datacenter.
• API/CLI automation support (e.g., API scopes; doctl requirements; infrastructure-as-code modules).
• BYOIP (Bring Your Own IP) is supported for IPv4 blocks using similar interfaces/APIs.

Important scoping note: Reserved IPs are a networking feature for Droplets and are not the same as App Platform static egress IPs or Load Balancer IP behavior.

• Primary users: developers, small and mid-sized teams, and SMBs operating services on Droplets that require a stable public endpoint or a simple active/passive failover.
• Common scenarios:
  • Replacing a Droplet while keeping the same public IP
  • Blue/green cutovers for a single public endpoint
  • Active/passive high availability with a failover script
  • Maintaining allowlists at partner systems that require a fixed source IP (often for egress; implementation details vary)

Reserved IPs are part of DigitalOcean’s Networking product set alongside Load Balancers and Cloud Firewalls.
