TL;DR: Split domain portfolios increase renewal drift, inconsistent DNS controls and accountability gaps, according to MarkMonitor. Domain governance becomes harder to audit when ownership, access and lifecycle decisions are scattered across registrars.
Editorial analysis by NHI Mgmt Group, based on content published by MarkMonitor: “How to Manage Multiple Domain Names Efficiently: An Enterprise Guide”.
Key questions
Q: Why do split domain portfolios create risk?
A: Split domain portfolios create risk because different registrars, owners, and DNS controls make it easier to miss renewals, lose transfer keys, or apply inconsistent security settings.
Q: How does consolidating domain names work?
A: Consolidating domain names means moving registrations and DNS management into fewer controlled accounts, with standardised ownership, transfer lock settings, renewal processes, and access reviews.
Q: How should teams inventory a domain portfolio?
A: Teams should inventory every registered domain, registrar account, DNS zone, renewal date, owner, business purpose, and linked services in a single authoritative register.
Practitioner guidance
- Build a complete domain inventory Record every domain, registrar, expiry date, DNS configuration, redirect status and internal owner in one system of record.
- Classify domains by business criticality Separate primary brand domains, defensive registrations, ccTLDs, campaign names and legacy redirects so security controls can vary by risk.
- Standardise approval and change policy Define who can request, approve and modify domains, and specify when a domain should be redirected, blocked, sold or retired.
Bottom line: Fragmented domain portfolios create inconsistent security controls, weaker accountability and avoidable renewal risk.

Registrar sprawl is a governance failure, not an administrative inconvenience. When domain records, renewal responsibility and change authority are scattered, the organisation cannot consistently prove who controls the asset. That creates the conditions for missed renewals, unauthorised changes and inconsistent protection levels. For practitioners, the first question is not which registrar to prefer, but whether the portfolio has a defensible control model at all.
A few things that frame the scale:
- Only 5.7% of organisations have full visibility into their service accounts, according to the Ultimate Guide to NHIs.
A question worth separating out:
Q: When should organisations prioritise registry locking?
A: Organisations should prioritise registry locking when a domain is business-critical, publicly trusted, or exposed to takeover impact, especially for primary web, email, or authentication domains. Registry lock adds an extra manual approval step at the registry before changes such as transfer, deletion, or name server updates can occur.
