+<ReleaseNote date="2023-12-07" title="Anycast flag releasing soon for GeoIP web services and databases">
+
+We’re adding a flag to identify Anycast networks in our GeoIP geolocation
+databases to help identify instances where we might not provide geolocation for
+a particular IP address due to Anycast routing.
+
+Most home and office networks rely on Unicast routing, where every node on the
+network is assigned a unique IP address. Anycast routing allows multiple servers
+to share the same IP address.
+
+**GeoIP web services**
+
+The Anycast flag will be available in all GeoIP web services by the end of
+December. For GeoIP web service users this will be a non-breaking change.
+
+We will post a new release note once the Anycast data point is available.
+
+**GeoIP databases**
+
+The Anycast flag will have a staggered release for GeoIP geolocation database
+users. The Anycast flag will be released for MMDB users by the end of December,
+at the same that the flag is available in the GeoIP web services. The flag is a
+non-breaking change for MMDB format database users.
+
+The Anycast flag will be released in CSV format databases in mid-January, 2023.
+In most cases, the addition of a new field to CSV databases should also be a
+non-breaking change, but you should check your integration to make sure that the
+it can accomodate the addition of new fields.
+
+The field will be present in the following GeoIP databases:
+
+- GeoIP Country database
+- GeoIP City database
+- GeoIP Enterprise database
+
+**GeoLite databases**
+
+The Anycast field will also be added to the CSV version of GeoLite geolocation
+databases, but the new field will be blank. This will allow the GeoIP databases
+to continue to be drag-and-drop replacements for GeoLite databases, so that it's
+easy to upgrade. The field will be present in the following GeoLite databases:
+
+- GeoLite Country database
+- GeoLite City database
+
+**Preparing for updated CSV format databases**
+
+MMDB format databases will be able to access the new data through our client
+APIs. If you are a CSV user, the following details may be helpful in preparing
+your integration for the new data.
+
+- If you're not sure whether you're using the MMDB format, the CSV format, or
+  both, you can
+  [learn how to check your account's database download history to determine whether you are downloading CSV files on our Knowledge Base.](https://support.maxmind.com/hc/en-us/articles/4407114914843)
+
+- The new field will be added to the Blocks CSV files:
+  `{GeoIP2,GeoLite2}-{Enterprise,City,Country}-Blocks-IPv4.csv` and
+  `{GeoIP2,GeoLite2}-{Enterprise,City,Country}-Blocks-IPv6.csv`
+- The new field name will be `is_anycast`, will be added to the right of
+  existing fields, and the cell will either contain 1 (if the network is an
+  Anycast network) or be blank (if it is not). The overwhelming majority of
+  networks are not Anycast, and so this field will be blank in most cases.
