IPQS
Lua Database Reader
About the Lua Database Reader

The Lua database reader allows your Lua application to use the on-premise IPQS IP reputation database and make informed decisions about IP addresses.

Installation

The Lua database reader is available as a "rock" from LuaRocks. Run the following command:

luarocks install ipqs-db-reader 

Usage

The following example shows how you can use the Lua database reader in your application to determine if an IP address is a proxy.

Due to the nature of IEEE-754 floating-point representation, floating-point values may display misleading precision. For example, 32.51, when converted to little endian hexadecimal representation, is: 0x3D0A0242, which, if interpreted literally, actually represents 32.509998321533 in Lua. Our Latitude and Longitude values should be interpreted as accurate to 2 (rounded) decimal places (e.g., string.format("%.2f", record:get("Latitude"))).

 

Note: Each database only holds either IPv4 or IPv6 data. Therefore, you may need two instances of the reader available depending on your use case.

 

Record Table Indices

See the table below for most files' boolean values and default columns. Your particular file may have columns in addition to the default columns. Arbitrary columns may be queried with the record:get("ColumnName") syntax. Speak with your IPQS representative if you have any questions about your flat file database.

 

Field Type Description
record.is_proxy boolean Is this IP address suspected to be a proxy? (SOCKS, Elite, Anonymous, VPN, Tor, etc.)
record.is_vpn boolean Is this IP suspected of being a VPN connection? This can include data center ranges which can become active VPNs at any time. The "proxy" status will always be true when this value is true.
record.is_tor boolean Is this IP suspected of being a TOR connection? This can include previously active TOR nodes and exits which can become active TOR exits at any time. The "proxy" status will always be true when this value is true.
record.is_crawler boolean Is this IP associated with a confirmed crawler from any of the following search engines: Baidu, Google, Bing, Yahoo, Yandex, Sogou, Exabot, DuckDuckGo, Facebook, Twitter, Pinterest, Naver, UptimeRobot, AppleBot, ArchiveBot, CoccocBot, YisouBot, PetalBot, ByteDance, or MailRU.
record.is_bot boolean Indicates if bots or non-human traffic has recently used this IP address to engage in automated fraudulent behavior. Provides stronger confidence that the IP address is suspicious.
record.recent_abuse boolean This value will indicate if there has been any recently verified abuse across our network for this IP address. Abuse could be a confirmed chargeback, compromised device, fake app install, or similar malicious behavior within the past few days.
record.is_blacklisted boolean This value will indicate if the IP has been blocklisted by multiple third-party agencies for spam, abuse or fraud.
record.is_private boolean This value will indicate if the IP is a private, non-routable IP address.
record.is_mobile boolean This value will indicate if the IP is likely owned by a mobile carrier.
record.has_open_ports boolean This value will indicate if the IP has recently had open (listening) ports.
record.is_hosting_provider boolean This value will indicate if the IP is likely owned by a hosting provider or is leased to a hosting company.
record.active_vpn boolean Identifies active VPN connections used by popular VPN services and private VPN servers.
record.active_tor boolean Identifies active TOR exits on the TOR network.
record.public_access_point boolean Indicates if this IP is likely to be a public access point such as a coffee shop, college or library.
record.connection_type string Classification of the IP address connection type as "Residential", "Corporate", "Education", "Mobile", "Data Center", or "Unknown".
record.abuse_velocity string How frequently the IP address is engaging in abuse across the IPQS threat network. Values can be "high", "medium", "low", or "none".
record.Country string

Two character country code of IP address or "N/A" if unknown.

record.City string

City of IP address if available or "N/A" if unknown.

record.ISP string

ISP if one is known. Otherwise "N/A".

record.Organization string

Organization if one is known. Can be parent company or sub company of the listed ISP. Otherwise "N/A".

record.ASN integer

Autonomous System Number if one is known. 0 if nonexistent.

record.Timezone string

Timezone of IP address if available or "N/A" if unknown.

record.Latitude float

Latitude of IP address if available or 0.00 if unknown.

record.Longitude float

Longitude of IP address if available or 0.00 if unknown.

record.ZeroFraudScore integer

The "strictness" = 0 fraud score for this IP address. See Proxy & VPN Detection for details about our fraud scores and the strictness parameter.

record.OneFraudScore integer

The "strictness" = 1 fraud score for this IP address. See Proxy & VPN Detection for details about our fraud scores and the strictness parameter.
