Verification guide

Verify InfoPrice crawler traffic

User-Agent strings can be spoofed. Network administrators should use the layered verification process below.

01Inspect requestUser-Agent contains a published token
02Match source IPAddress belongs to a published CIDR
03Check reverse DNSOptional when hostname strategy is published
04Confirm forward DNSHostname resolves to the same source IP
Production ranges are not configured yet

The prefixes list is currently empty. Do not treat an empty list as proof that an address belongs to InfoPrice.

1. Retrieve current network ranges

curl -s https://bot.infoprice.co/ips.json | jq

2. Inspect reverse DNS

dig -x 192.0.2.1 +short host 192.0.2.1

Replace the example address with the actual request source IP. A recognizable hostname is not sufficient by itself.

3. Confirm forward DNS

dig example.crawler-hostname.invalid A +short dig example.crawler-hostname.invalid AAAA +short

The forward lookup must include the original source IP. Until InfoPrice publishes a reverse DNS suffix strategy, use IP-prefix verification as the authoritative published network mechanism.

Machine-readable identity
