result

The result. This field is omitted in case of error
error

The error message. This field is omitted when a call is successful
count

The number of records returned
limit

The maximum number of elements
from

The IP netblock range that was passed in the request as an offset for the returned results.
next

If not null, it shows the value of the last IP netblock (inetnum) from the response, which can be substituted into the from parameter and get the next page, if the current response doesn't fit into the limit. Such pagination is only available for IPv4, IPv6 and ASN API requests. ORG requests don't support it.
inetnum

inetnumLast
The last IP as integer value
inetnumFirstString
The string representation of the inetnumFirst field. Use this field if you want to avoid exponential representations of the inetnumFirst field.
inetnumLastString
The string representation of the inetnumLast field. Use this field if you want to avoid exponential representations of the inetnumLast field.
