Vallocor Operational Edge & Probe Verification
Hosts and IP addresses resolving under *.vallocor-edge.eu (such as probe-nl-01.vallocor-edge.eu, probe-fr-01.vallocor-edge.eu, probe-pl-01.vallocor-edge.eu, and otlp.vallocor-edge.eu) are operated exclusively inside the European Union by Vallocor, a European B2B cybersecurity, observability, and NIS2/ISO compliance provider.
Strictly Non-Intrusive & Domain-Authorized Checks
If you observed a DNS lookup or HTTPS connection from a *.vallocor-edge.eu IP address in your logs, a user with a verified corporate email address on your domain requested a Passive Perimeter Audit on vallocor.eu, or your organization is an active Vallocor observability tenant.
- No active port scanning or fuzzing: Our engine never performs TCP SYN sweeps, directory brute-forcing, credential testing, or vulnerability exploitation.
- Standard protocol hygiene only: Checks consist solely of standard DNS queries (
SPF,DMARC,DNSSEC,CAA), a single standard TLS handshake / HTTP header check on port443, and passive public Certificate Transparency / OSINT lookups. - Identifiable HTTP signatures: Passive one-shot perimeter audits carry
User-Agent: Vallocor-Perimeter-Engine/1.0 (+https://vallocor-edge.eu; probe=<node>; abuse=security@vallocor.eu), while continuous tenant synthetic availability checks (app.vallocor.eu) carryUser-Agent: Vallocor-Synthetic-Probe/1.0 (+https://vallocor-edge.eu; region=<region>; abuse=security@vallocor.eu).
Reverse-DNS (FCrDNS) Verification
Security operations teams can network-verify whether an IP address genuinely belongs to Vallocor using Forward-Confirmed Reverse DNS:
# 1. Verify PTR record resolves to *.vallocor-edge.eu dig -x <OBSERVED_IP_ADDRESS> +short # Example output: probe-nl-01.vallocor-edge.eu. # 2. Confirm forward A / AAAA record matches the exact same IP dig probe-nl-01.vallocor-edge.eu A +short dig probe-nl-01.vallocor-edge.eu AAAA +short
Abuse Reporting & Permanent Domain Opt-Out
To permanently exclude your domain, ASN, or CIDR netblock from all Vallocor verification checks, or to report any operational concern, email security@vallocor.eu. Opt-out requests from verified network owners are applied across all *.vallocor-edge.eu nodes within one business day.
