To upload bulk addresses, use the form below. The input format is as follows

BASEIP,NETBLOCK_SIZE,COUNTRYCODE,STATE,CITY
or
BASEIP,NETBLOCK_SIZE,COUNTRYCODE,,CITY

... one entry per line in the uploaded text file. Each entry to start at column 0 and to have no spaces in the line unless the city-name requires it.

The State is only currently supported for the USA (not Canada). If you are outside this area, then simply leave it blank - that is, your line will then look like the second form above.

The base-ip should be the lowest IP address (in dotted-quad form, eg: 192.168.254.0) for the netblock defined by that line in the file you are uploading.

The netblock size defines the range of IP-space to classify for each line. It should be an integer between 9 and 24 (at the moment the smallest resolution is a /24, or class-C network and I simply won't believe you if you tell me you've located a /8 to a city :-).

The countrycode is a two-letter identifier for the country, the list of which are available here. Similarly, states are defined by two-character codes, the list of which is available here.

The city name is a text string, which must match up within the database for registration to take place. There is a map-based nameserver which you can use to verify that a given city is in the DB. Please let me know if you find a city that's not already in the DB.

As an example, the reference for this webserver would be

217.169.39.0,24,UK,,London
