Add MX and TXT queries to DnsService probing flows (initial, special, and deep scan) by removing the previous TXT-only conditional and explicitly querying DNS_MX and DNS_TXT. Extend sortRecords to include A, AAAA, MX, TXT, and CAA and sort by root (@) first, then by host, and by priority when present. Update DNS views to show a Host column for MX, TXT, and CAA tables, display @ as "@ (root)", and surface record source badges (manual/imported) next to the host for clarity.
Add comprehensive DNS management and input validation, plus safer transfer and logging behavior.
- Add CronHelper utilities for cron scripts and unify logging/formatting.
- Improve InputValidator: sanitizeDomainInput and validateRootDomain (handles multi-level TLDs) and use throughout domain import/create flows to reject subdomains.
- DomainController: refactor DNS refresh to support quick/deep discovery (background deep scans), add endpoints to discover, add/delete/bulk-delete DNS records, import BIND zone files, enrich IP metadata via enrichIpDetails, and strengthen bulk import/reporting messages.
- DnsRecord model: add source column handling (discovered/manual/imported), avoid auto-deleting manual/imported records, and add helpers for deleting, bulk deleting, manual adding and importing zone records.
- Tag, NotificationGroup and Domain transfer logic: unlink groups when ownership changes, remove tags that belong to other users, add audit logging via Logger and improved bulk transfer reporting. TagController/View: show transferable users for admins and skip global tags on transfer.
- Notification channels (Discord, Mattermost, etc.) and EmailHelper: allow explicit subjects and improve payload fields based on notification type.
- Add new migration 029_add_dns_record_source.sql and wire it into the installer; update migrations detection.
- Add new views/partials for confirm/import/transfer modals, update various domain/group/tag templates, and update cron scripts and routes for discovery.
These changes preserve manual/imported DNS records, improve root-domain validation, enable background deep discovery, and add better logging/audit trails for transfers and imports.
Introduce DNS monitoring: add DnsService (comprehensive DNS lookup, crt.sh discovery, Cloudflare detection, IP enrichment) and a new DnsRecord model to persist snapshots, manage diffs, and provide queries/stats. Update DomainController to support a dns_monitoring_enabled flag, refactor WHOIS/DNS refresh logic into performWhoisRefresh/performDnsRefresh, and add endpoints for refreshWhois, refreshDns and refreshAll; send notifications when DNS monitoring is toggled. Add UI templates/tabs for DNS, billing, notifications, overview, SSL and WHOIS and wire DNS data into the domain view; expose cached IP details. Add cron/check_dns.php and migration 027_add_dns_monitoring.sql (and include it in installer migration lists). Other tweaks: safer EmailHelper subject handling, TldRegistry search improvements, domain sorting using an effective status (expiring_soon), Discord channel null-safe fields, settings UI additions (domain_view_template and cron staleness warnings), and route/migration updates. This enables scheduled and manual DNS scans with persistent records and notifications.
