How does CANDDi identify Company Names from IP Lookup?

Follow

Summary:

One of the ways CANDDi obtains Company Identified and Location information is by using IP Lookup, however this is only an approximation (and there are always edge-cases where this doesn't work accurately).  This article looks at these edge-cases and how you can "train CANDDi" to improve relevance for your organisation

 

About Reverse IP Lookup:

When a visitor arrives on your website then CANDDi will perform a reverse IP lookup.  Essentially we're running a 

whois [ip address]

query to identify the registered owner of the IP address.  Wikipedia Article

 

For large corporations and organisations who have their own registered IP Address then this returns significant amounts of data (and allows CANDDi to make some solid assumptions about the organisation for whom this Contact may work for / what organisation is on your website).  

For example:

whois 195.195.44.51

whois 195.195.44.51

inetnum: 195.195.44.0 - 195.195.47.255
netname: WALCAT-2
descr: Walsall College of Arts and Technology
country: GB

address: Walsall College of Arts and Technology
address: St. Paul's Street
address: Walsall, WS1 1XN
address: United Kingdom
phone: + 44 1922 657000

This publicly available data is telling us that the Contact who visited from behind IP address 195.195.44.51 was browsing from within Walsall College of Arts and Technology.

 

CANDDi's Display:

CANDDi believes that our mission is to display all the raw (and processed) data to you (the customer) in a manner which makes it simple to understand (but so that you can drill down to identify the source of the raw data if / as required).

 

IP records are displayed in the "IP Address" in the Contact View

You can also build streams and filters using this data.

If CANDDi identifies a location/company name then these are displayed on the map/in the personal widget.

 

Problems with IP Lookup (and how to report):

IP Lookup is very effective as a means of identifying larger organisations who have their own static IP addresses. Unfortunately, there are two cases where it falls down

1. The visitor is browsing from a mobile device (phone/tablet) over mobile network-

If the visitor is browsing your site using a mobile device using wifi then the IP address reported will be the IP address of the fixed wifi device (and hence will report the "corporate details").  However, if the visitor is browsing using a mobile device on the mobile network (over 3G etc..) then the IP address will be registered to one of the major mobile networks (Vodafone, O2 etc..).  In this case, CANDDi will filter the Company Name (and the Location) and will report this Visitor as having "(no company yet)".

 

2. The visitor is browsing from a dynamic IP address (or an IP address registered to an ISP)-

If the visitor is browsing your site from a connection with a dynamic IP address or an IP address registered to an ISP (this is the case for most home broadband users or for most small businesses) then the IP address is registered to the ISP (and the location of the IP address is typically the head office for the ISP)

Before displaying any data from IP lookup, CANDDi runs the data through an ISP filter.  This is a blacklist of "known ISP's".  So you won't see anyone on your site who works for "Sky Broadband". In this case, CANDDi will filter the Company Name (and the Location) and will report this Visitor as having "(no company yet)".

However, our ISP filter sometimes misses out ISPs (we're constantly keeping it up to date - but there are lots of ISPs out there).  In this case, CANDDi might report the company name incorrectly (and the location lookup incorrectly too). If that happens, let us know and we will update the record.

 

You can help train CANDDi by reporting an ISP (see: https://support.canddi.com/hc/en-gb/articles/201956237
