* collect_domain_info.py: add curl fallback for blocked/broken fetches Many sites that returned no usable homepage under the original requests fetch turned out to be soft-failures: misconfigured TLS certs (self-signed, hostname mismatch, weak chain), 403/captcha pages from User-Agent-based bot filters, or redirect chains the requests stack rejected. None of those recover under a single retry with the same client config. This wires a curl fallback into _fetch_homepage that triggers when the primary attempt errors or returns a non-2xx status. Curl runs with -k (skip TLS verify), -L (follow redirects), --max-time bound, and a real-browser User-Agent string -- enough to clear the common UA-block and bad-cert classes of failure that small ISPs and regional telcos routinely ship. A 2xx-with-empty-head response is left alone (parked pages do not improve on retry). When both attempts fail, the error column carries both signatures so it is obvious that the fallback was tried. Smoke-tested against eight previously-failed cert-error domains: six recovered full title/description (as1101.net, citictel-cpc.com, xtrim.com.ec, etecsa.cu, zillion.network, sandia.gov), two remained genuinely unreachable. Happy-path domains take the primary path unchanged. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * Bulk reverse-DNS map coverage: top-500 ASN audit + KU re-research Two passes against the bundled IPinfo Lite MMDB and the existing known-unknown list, both classified under the two-corroborating-sources rule (AGENTS.md): 1. Top-500 unmapped ASN-domain audit. Walked every record in ipinfo_lite.mmdb to find as_domain values not yet in the map, ranked by routed IPv4 count, took the top 500 (>= ~/15 each), and ran them through collect_domain_info.py. Yield: 435 new map rows from operators with two or more independent corroborating sources; 65 entries to known-unknown for operators where homepage and WHOIS were both unavailable from the test environment. Recovered domains span ISPs, web hosts, IaaS/MSP/MSSP, education networks, government agencies, and a long tail of major industrials. 2. Full re-research of the existing 3,606-entry known-unknown file using the new curl fallback (separate commit). The fallback recovered homepage content for 1,686 of 3,670 (45.9%) previously dark domains. Of those, 770 had a corroborating WHOIS or as_name alongside; 508 cleared the strict service-category test and were promoted out of known-unknown into the map. The remaining 262 recovered titles were brand-only / login-portal / under-construction pages where service category could not be assigned with confidence. Also removed a stale "#name?" Excel auto-correction artifact from the known-unknown file (it would never have matched any real reverse-DNS base domain). Cumulative result: base_reverse_dns_map.csv 3,946 -> 4,889 rows (+943, +23.9%); known_unknown_base_reverse_dns.txt 3,606 -> 3,162 (-444 net after both batches plus the artifact). Every promotion has two independent sources for the operator's identity and a homepage or MMDB-as_name signal sufficient to assign a service type. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * Fix chello.sk classification: UPC, not Liberty Global The original classification aliased chello.sk to "Liberty Global" based on the IP-WHOIS netname (LGI-INFRASTRUCTURE) plus a stale homepage redirect to ziggo.nl that the collector observed at fetch time. This broke the AGENTS.md rule that IP-WHOIS only counts as a corroborating source when the domain name matches the netname -- "chello" does not match "LGI", so the IP-WHOIS should not have been treated as a source. The WHOIS was unambiguous: UPC BROADBAND SLOVAKIA, s.r.o. UPC retains its consumer brand in Slovakia (unlike Ireland, where upc.ie was rebranded as Virgin Media Ireland in the existing map). Reverting to the operator brand per WHOIS. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * Fix vodafone.is classification: Sýn, not Vodafone Same pattern as the chello.sk fix in the previous commit: the historic brand recorded in the MMDB as_name (Vodafone Iceland) is no longer the operator. Sýn acquired Vodafone Iceland's operations and the homepage redirects to syn.is, presenting Vodafone only as a partner relationship rather than an active sub-brand. Following the upc.ie -> Virgin Media Ireland precedent for rebranded markets, the canonical attribution is the current operator. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * AGENTS.md: codify the homepage-redirect disambiguation rule Three classification mistakes during the bulk batch (chello.sk, vodafone.is, telia.dk, apogee.us) all came from the same gap in the workflow: when a homepage's final URL is a different host from the domain being classified, the right brand depends on the *relationship* between the two domains, not on the WHOIS or as_name in isolation. Adds a new step 6 to the unknown-domain classification workflow that spells out the three patterns and the disambiguator: - Acquisition / rebrand: the homepage shows the acquiring operator's marketing site. Use the new operator. MMDB as_name and IP-WHOIS netname are commonly stale for years post-acquisition; do not let them override an unambiguous current-operator homepage. - Sister brand / shared infrastructure: the homepage redirects to a *sibling* brand under the same parent group, but the WHOIS for the original domain still names a *specific* current operator. Use the WHOIS operator, not the redirect target. Canonical cautionary tale: chello.sk (WHOIS: UPC BROADBAND SLOVAKIA) was originally classified as Liberty Global because the homepage redirected to ziggo.nl (a sibling Liberty Global brand). The right answer was UPC. - TLD or subdomain variant: same operator, different domain. Trivial. Renumbers the remaining steps. The IP-WHOIS rule (step 5) and the two-source rule (now step 8) are unchanged but cross-referenced. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * Apply homepage-redirect rule to telia.dk and apogee.us Same pattern as chello.sk and vodafone.is in earlier commits — the historic operator name in the MMDB as_name and WHOIS does not reflect who actually runs the IPs after an acquisition. The homepage redirect is the current ground truth. - telia.dk -> Norlys: Norlys acquired Telia Denmark; homepage now redirects to shop.norlys.dk and presents Norlys throughout. - apogee.us -> Boldyn: Boldyn acquired Apogee Telecom; homepage now redirects to boldyn.com and shows the Boldyn marketing site for higher-education managed services. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * Bulk reverse-DNS map coverage: next-500 unmapped ASN-domain audit Same workflow as the first top-500 batch in this branch, applied to the next tier of unmapped MMDB as_domain values (ranked 501..1000 by routed IPv4 count, each ~/15 to /14.5). Pre-screened against the current state of base_reverse_dns_map.csv and known_unknown_base_reverse_dns.txt. Yield: 414 newly-classified map entries + 86 known-unknown additions. Type breakdown skews ISP-heavy as expected at this scale, with strong representation from Education (universities now reaching deeper into the long tail), Government (state/county/national agencies), Web Host (regional hosting providers), and IaaS (mid-market cloud). Applied AGENTS.md step 6 (homepage-redirect disambiguation) on every case where the homepage's final_url crossed hosts: kept new operator when the redirect target was an acquiring brand (e.g. atlanticmetro.net -> 365 Data Centers, performive.com -> CloudFirst, fasternet.com.br -> Desktop, eatel.com -> REV, blic.net -> Supernova, dimensiondata.com -> NTT DATA, virtela.net -> NTT Communications), used WHOIS operator when the redirect was sister-brand or shared infra, used the same operator when the redirect was a TLD/subdomain variant. Coverage delta: 88.89% -> 90.40% of MMDB IPv4 (+1.51 pp, ~47M IPv4). Cumulative for this PR: 85.10% -> 90.40% (+5.30 pp, ~165M IPv4). Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * Reclassify the 262 left-dark KU re-research candidates with relaxed heuristic Of the 770 two-source candidates from the curl-fallback KU re-research pass earlier in this branch, 262 had homepage content and a corroborating WHOIS/as_name but were left in known-unknown because the homepage was brand-only or a login portal that didn't directly describe service category. Relaxing the heuristic on a re-pass: when the WHOIS legal name itself contains a regulated-telecom keyword (TELECOM, TELECOMUNICAÇÕES, INTERNET, FIBRA, BROADBAND, PROVEDOR DE INTERNET, NET TELECOM), that *is* a service-category source -- in Brazil, Argentina, Chile, and peers, operators must register under specific legal naming and the registration is a regulator-vetted signal. Combined with two-source identity, that clears the bar without forcing the homepage to also spell out the service. Same goes for brand-name-as-service signals: "X Server Limited" with a customer-portal homepage and matching WHOIS reasonably maps to Web Host; "X Fiber" + matching as_name maps to ISP. These are what readers would naturally infer from the operator's own self-naming. Yield: 95 promotions out of 262 (36% of the left-dark subset). The remaining 167 stay in known-unknown because the homepage was a generic placeholder ("Index of /", "Coming Soon", default Apache page), the brand on the homepage didn't match the WHOIS, the operator was clearly a non-telecom (e.g. INPASUPRI = supplies for IT, malugainfor = Comércio de Produtos de Informática, hugel = pharma), or the service category was genuinely ambiguous. MMDB IPv4 delta is small (+0.03 pp, +888K IPv4) since most of these are long-tail operators with low or zero MMDB footprint -- the value is in PTR-side attribution coverage when these brands appear in actual reverse-DNS reports. Cumulative for this PR: map 4,889 -> 5,398 rows; KU 3,162 -> 3,153 lines; MMDB IPv4 coverage 88.89% -> 90.42% (+1.53 pp from the next-500 batch plus this re-pass).
