Babbar SAS is a French SEO company and the operator of the Barkrowler crawler and AS210743. Public evidence confirms its incorporation, ASN registration, and published crawler identifiers, but no live BGP snapshot or personnel data are available. The main watchpoints are updates to the official IP-range JSON and AS210743 routing changes, as these directly impact bot traffic attribution and SEO analytics reliability.

Babbar SAS

Babbar SAS is a French SEO and web-crawling company operating the Babbar.tech platform and the Barkrowler crawler, with its autonomous system AS210743 serving as the network origin for its crawler traffic.

Why It Matters

Changes in AS210743 routing, the official Barkrowler IP-range JSON, or the crawler’s behaviour directly alter how site operators attribute bot traffic and how SEO professionals trust Babbar’s backlink and semantic metrics. Unnoticed shifts can silently distort web analytics and security postures.

What Public Sources Show

Babbar SAS is a French technology company based in Evreux that operates the Babbar.tech search-engine optimisation platform and the Barkrowler web crawler. Publicly, it is also the organisation behind autonomous system AS210743 (BABBAR-AS), which routes crawler traffic onto the internet. Its dual identity—an SEO analytics vendor and a network operator—makes it relevant to site owners, security teams, and anyone who tracks bot behaviour.

The Barkrowler crawler, identified by the user-agent Barkrowler and a reverse-DNS suffix of babbar.eu, collects public web pages to build Babbar's web graph. This graph fuels the company's SaaS platform, which sells backlink, semantic and domain-authority metrics to SEO clients. Crawler traffic originates from AS210743, which peers upstream with Cogent Communications (AS174) and announces several IPv4 prefixes.

Babbar publishes an official IP-range list to help site operators configure allowlists or blocklists.

French corporate records show Babbar SAS was founded in November 2019 with SIREN 879 721 942 and an address in Evreux. Registry lookups from RIPE NCC, Cloudflare Radar and bgp.tools link the company to AS210743, assigned on 17 September 2021 under ORG-BA1424-RIPE. Babbar’s own terms page ties the RCS number 879 721 942 to its service, corroborating the corporate identity.

When Barkrowler crawls a site, its requests show in logs and analytics. Operators who fail to identify the bot may misattribute traffic or inflate visit counts. SEO professionals who depend on Babbar’s backlink and semantic metrics rely on the crawler’s web graph, whose freshness can be affected by routing changes.

A shift in the official IP ranges, user-agent, or upstream connectivity silently alters both the bot’s footprint and the analytics output, making continuous monitoring important.

The most concrete control points are AS210743’s route origin, the Barkrowler IP-range JSON file hosted at babbar.tech, and the crawler’s documented reverse-DNS pattern. At the time of writing, the official JSON lists only two /24 prefixes (217.113.194.0/24 and 154.54.249.0/24), yet public BGP data shows a third prefix (217.113.196.0/24) and IPv6 announcements.

The upstream relationship with Cogent Communications (AS174) means that changes in Cogent’s routing policies or Babbar’s peering arrangements could redirect crawler traffic onto new paths without notice.

Several data gaps create uncertainty. The official IP-range JSON omits 217.113.196.0/24 that appears in some BGP data, and no live routing snapshot has been collected. Without real-time BGP, the actual set of prefixes used by Barkrowler could differ from published lists. In addition, no individual executive or technical lead has been publicly verified for Babbar SAS, limiting the ability to attribute operational decisions or accountability.

Practical watchpoints include changes to the Barkrowler IP-range JSON, new prefix announcements or withdrawals via AS210743, and modifications to the company’s SIREN registration or RIPE WHOIS record. Any revision to the official crawler page or the terms of service could also signal a shift in policy. For site operators, monitoring these signals helps maintain accurate bot management rules and ensures that SEO analytics remain trustworthy.

Operating Surface

Babbar SAS operates a SaaS and API platform for backlink, semantic, and web-graph metrics, while its Barkrowler crawler collects public-web data at scale. In network-infrastructure terms, the company appears as the organisation behind AS210743/BABBAR-AS, publishing official crawler IP ranges to facilitate bot management.

Babbar’s dual role as an SEO analytics provider and an internet-scale crawler operator matters because changes in its routing, IP ranges, or platform coverage directly influence both web traffic attribution and the quality of SEO intelligence sold to customers. Site operators and security teams must be able to identify and govern Barkrowler traffic.

Watchpoints

Babbar SAS fits into the category of commercial web crawlers that double as infrastructure operators. Its control over AS210743 and published crawler IPs makes it a manageable, attributable bot; however, discrepancies between official and BGP-visible prefixes mean monitoring must combine registry, routing, and on-site log data to avoid blind spots.

Monitor barkrowler-ip-ranges.json for additions or removals; track AS210743 BGP announcements for prefix churn or upstream changes; watch for Babbar SAS corporate record updates that could signal reorganisation or ownership change.

No current BGP snapshot is available, so the live prefix set is unconfirmed. The absence of named individuals means we cannot map decision-making authority for network operations or commercial strategy. No revenue or customer data constrains assessment of market influence.
