Dropped vs Expired vs Deleted Domains: Terms Explained

Why the vocabulary matters

Take the sentence "that domain dropped." It might mean the owner let it lapse, the registrar deleted it, a registry purged it, or it simply stopped resolving for a day. Each reading leads to a different action: wait, bid, register now, or ignore it. The terms below are used here in the sense that follows ICANN's EPP status definitions and the general convention in the domain industry. Where usage differs between registries, the text says so.

Terminology table

Term	Plain meaning	Who acts	Can the owner still recover it?	Can anyone else register it?
Expired	The paid term ended and was not renewed	Nobody yet; time passed	Yes, usually by renewing at the registrar	No
In grace (auto-renew period)	The registry renewed the name automatically after expiry; the registrar may reverse it	Registry and registrar	Yes	No
Deleted	The registrar sent a delete command to the registry	Registrar	Usually yes, through redemption, often at extra cost	No
Redemption period	A holding window after deletion, about 30 days in most generic TLDs	Registry	Yes, through restore, normally with a fee	No
Pending delete	The final stage before purge, about five days for most generic TLDs	Registry	No, in most cases	Not yet; it opens when purged
Dropped	Purged from the registry and open to new registration	Registry	No, the old registration is gone	Yes
On hold	Delegation switched off; the name stays registered	Registrar (client hold) or registry (server hold)	Yes, once the cause is resolved	No
Suspended	Taken out of service, usually for abuse, legal or verification reasons	Registrar or registry	Depends on the cause and policy	No

ICANN's EPP status code guide defines redemptionPeriod as a 30-day hold after a registrar-requested deletion, followed by pending delete, and describes clientHold and serverHold as statuses that stop a name from being active in DNS. The same page gives no fixed length for the auto-renew grace, only a limited period.

Each term in more detail

Expired

"Expired" is a statement about money and time, not about the registry's state. An expired name may still sit in the zone with its normal name servers, since expiry on its own does not always trigger a technical change. Registrars frequently swap in their own parking name servers, which can produce a zone-file change without removing the name.

Deleted

A deletion is something a registrar does, sending a command to the registry. A registrar can delete a name at expiry, during the grace window, or at the owner's request. Registrars also delete names on their own initiative, for example after payment disputes. Deletion in a generic TLD does not mean the name is gone; it begins the redemption sequence described in the domain lifecycle.

Dropped

The word "drop" comes from the industry's habit of saying a name "drops" from the registry's database. In strict use, a dropped name is one that has been purged and can be registered again. In looser use, including some lists, "dropped" means any removal from a zone. Whenever you see a "dropped domains" list, check which meaning it uses.

Pending delete and redemption

These are the two registry-side holding stages after deletion. During redemption the owner can restore; during pending delete the name has finished its chance to be recovered. If a list claims names are "pending delete" it is giving a schedule: names that will drop within days.

On hold and suspended

These are the confusing ones because the zone-file effect can be identical to deletion. A registrar sets clientHold for reasons that include unpaid invoices and unverified contact details. A registry sets serverHold in response to legal orders or abuse findings. Neither means the registration is about to be released. See the section on ambiguity below.

How zone-file diffing interprets each state

A zone file lists the names a TLD currently delegates, along with their name-server records. Comparing consecutive daily snapshots produces three simple sets: names added, names removed, and names that stayed with changed records. The following table maps the lifecycle terms onto what such a comparison would show. It describes typical behaviour, and registries differ, so verify the extension you care about.

State	Typical zone-file appearance	What the diff shows
Expired, owner and registrar inactive	Often still present, name servers may change to parking	Usually nothing, or a name-server change
Auto-renew grace	Often present	Usually nothing
Client hold	Not present (no delegation)	Appears as a removal
Server hold	Not present	Appears as a removal
Redemption period	Typically not present	Appears as a removal, usually about 35 days before release
Pending delete	Typically not present	Already removed; nothing new on the diff
Dropped, then re-registered	Present again with new name servers	Appears as an addition, indistinguishable from any new name unless you remember the earlier removal
Restored by owner	Present again, often with the old name servers	Appears as an addition after a removal

A worked diff

Suppose two consecutive snapshots of a hypothetical extension. The labels are invented.

Day 1 zone:   alpha-test.example  beta-test.example  gamma-test.example
Day 2 zone:   alpha-test.example  gamma-test.example  delta-test.example

removed: beta-test.example
added:   delta-test.example

The removal of beta-test.example tells you only that its delegation ended. Interpretation needs more evidence. Its RDAP record would show redemptionPeriod if it was deleted, clientHold if its registrar placed it on hold, or serverHold if the registry did. Only a fourth outcome, "not found", suggests that the name has already been purged. The addition of delta-test.example is a new delegation: either a brand-new registration, a re-registration after a drop, or a restore.

Reading a removal correctly

Ask four questions

1. Did it come back? If the name reappears within days, it was probably a hold or a restore, not a drop.
2. What does RDAP say right now? The status values separate hold from deletion. See WHOIS vs RDAP.
3. How long has it been gone? Under about a month suggests the redemption stage. Past the redemption window, the name may be in pending delete.
4. Does the registry follow the standard sequence? Some registries, including many country-code ones, use different periods or no redemption stage at all.

Common misreadings

• "Removed means available." It almost never does on the same day. Availability starts at the purge, not the removal.
• "Added means new." A name added to a zone could be a new registration, a re-registration after a drop, or a restoration.
• "Present means active." A name present in the zone could be expired, parked, or already queued for deletion.
• "Absent for a day means dropped." Registries sometimes withdraw and re-publish names because of technical problems, and holds often resolve within days.

Registry differences

The table at the top reflects the convention for generic TLDs, where ICANN's consensus policies set minimums such as the 30-day redemption period. Country-code registries make their own rules. Some have no redemption period, some use different grace lengths, and some release names on a fixed schedule. Newer generic extensions follow the ICANN baseline but can add stages of their own for premium names or promotional pricing. When a guide, seller or list uses one of these terms for a country-code domain, read it as a loose label until you have the registry's policy in front of you.

For definitions beyond these six terms, the domain glossary collects the rest of the vocabulary. To browse removals themselves, the expired domain lists show daily removals by extension.

Wording to use in your own notes

Precise labels in a spreadsheet or alert save arguments later. A short convention that holds up across registries is to record the evidence rather than the conclusion. Write "left zone on 3 May, RDAP shows redemption" instead of "dropped". Write "present in zone, expiry date passed" instead of "expired and available". When a name later returns, the earlier note shows whether it came back as a restore, a re-registration or a hold that ended.

The same habit helps when you read other people's claims. A seller who says a name "just dropped" may be pointing at any of the removals in the table above. Ask which one, and ask for the status record. A claim that cannot be matched to a status is a claim about marketing, not about the registry.

A quick decision guide

• Name present in the zone and past its expiry date: the owner can renew, so do not plan around it.
• Name missing from the zone for under a month, status shows redemption: the owner can still restore, so wait.
• Name missing and status shows pending delete: a release is days away, so decide on a backorder route now.
• Name missing and the lookup says not found: try registering it at a registrar.
• Name missing but the status shows a hold: nothing is about to be released, so move on.

Frequently asked questions

Is a deleted domain the same as a dropped domain?

Not quite. A deletion is a registrar's command, which starts the redemption and pending-delete stages. A drop is the registry's final purge, after which the name can be registered again. Many sources use the two words interchangeably.

Why does a domain disappear from the zone but stay unavailable?

Removal from the zone means the name is no longer delegated. It may be on hold, suspended, in redemption or in pending delete, all of which keep it registered or reserved. Check the status in RDAP before assuming it is free.

What is the difference between clientHold and serverHold?

clientHold is set by the registrar and serverHold by the registry. Both stop the name from resolving. The reasons differ: registrars use it for billing or verification issues, registries use it for legal or abuse actions.

Does "pending delete" mean I can register the domain?

No. Pending delete is the final holding stage, around five days for most generic TLDs, before the registry purges the name. Registration becomes possible only after the purge.

Can I tell expired from suspended by looking at a zone file?

Not reliably. Both can look like a removal, or like nothing at all. You need the registration status from RDAP or a registrar to tell them apart.

Do ccTLDs use the same terms?

Many use similar words, but periods and rules differ by registry. Treat the terms as approximate and read the specific registry's policy.
