Domain Drop Catching: How Expired Names Are Grabbed

Every day, a large number of domains reach the end of their lifecycle and are deleted by their registries. Most are names nobody will miss. A small share are short, generic or still attached to backlinks and traffic, and those are usually registered again within a second or two of their release. That race is drop catching.

What is drop catching?

Drop catching is the practice of registering a domain at the exact moment the registry deletes it. The name has already been through its grace period, its 30-day redemption period and 5 days of pending delete. At the end of that, it is removed from the registry database and becomes available to whichever registrar asks first.

Asking first is the whole game. The registry doesn’t hold a lottery or an auction for dropping names. It processes incoming create commands in order. Whoever’s request arrives the moment the name is free wins.

How the drop works at the registry

Registrars talk to the registry over EPP connections. Each accredited registrar gets a limited number of connections and a limited rate of commands, so that no single party can flood the system. At drop time, a registrar can therefore only fire so many registration attempts per second.

Drop-catching services get around this by operating many accredited registrars, sometimes hundreds, each with its own connections. Together they can send far more attempts in the first seconds than any single registrar. That is also why ordinary registrars almost never win a contested drop.

Drop catching services and their pricing

Catching services usually work on a pay-on-success model. You place an order for a name. If the service catches it and you are the only customer, you pay a fixed fee that includes the first year. If several customers ordered the same name at that service, it goes to an auction between them, often private.

There is no reliable public data on success rates, and figures you see on a service’s own site are marketing. What you can say is that competition concentrates on a few names. For most of the deleted names on a given day, nobody places an order at all.

Some services also buy names before they drop, from registrars that auction their expiring inventory. If your target name is held at a registrar that does this, it may never reach the public drop. More on that route in domain backorder.

How to catch a dropping domain yourself

For low-competition names, you can do it yourself. The plan:

1. Confirm the status. pendingDelete means the drop is about five days away.
2. Watch the status shortly before and during the expected window.
3. Register the moment the lookup returns “not found”.

A small script makes the watching easier. This one checks a .com every ten minutes and stops when the registry no longer has a record:

#!/usr/bin/env bash
DOMAIN="example.com"
while true; do
  CODE=$(curl -s -o /tmp/rdap.json -w "%{http_code}" \
    "https://rdap.verisign.com/com/v1/domain/$DOMAIN")
  if [ "$CODE" = "404" ]; then
    echo "$(date -u) $DOMAIN no longer registered"; break
  fi
  echo "$(date -u) $(grep -o '"status":\[[^]]*\]' /tmp/rdap.json)"
  sleep 600
done

Then register through a domain search or, if you want to automate the last step too, through a registrar API. For anything others are likely to want, this approach will lose to a professional catcher. For a forgotten personal name or an old project domain, it often works fine, sometimes hours after the drop.

Drop catching .de and other country codes

Country codes have their own deletion rules and their own drop. A .de domain becomes free for everyone once DENIC’s 30-day redemption grace period after deletion is over. DENIC’s domain query shows names in that phase as deleted and in the cooling-off period, so you can see a release coming. Catching services operate on .de as well.

.eu names become available after the 40-day quarantine that follows deletion. .uk names are cancelled around 90 days after expiry. Each registry has its own release process, and a service that is strong on .com may not be active on these at all. The lifecycle details for different endings are in expired domains.

Where drop catching goes wrong

Catching a name doesn’t give you rights beyond the registration. If the name matches a company’s trademark, especially one that is still in use, a UDRP complaint for gTLDs or a court case for .de is a real risk. The fact that the previous holder let it lapse doesn’t change that.

Dropped names also carry history. Old backlinks can come from spam networks, and the name can sit on email blocklists. Check the name in the Wayback Machine and look at what it was used for before you bid. Google’s spam policy on expired domain abuse targets sites that reuse a dropped domain’s reputation for unrelated content.

Is it worth trying?

For a name that fits your project and isn’t a hot property, yes. Watch it yourself and register at the standard price, which for a .com is €14.99. For a contested name, place an order with a catching service, set an auction limit, and keep a fallback. The exact phases leading up to the drop are listed in when a domain becomes available.
