Tools

• desec_create_rrset ~515 tokens
  WRITE: create ONE new RRset (a set of DNS records of one type at one name) in a domain. It goes live in DNS immediately and a wrong record can take a site or mail offline. Fails if an RRset with this subname and type already exists (use desec_replace_rrset for that) or if a CNAME would conflict with
• desec_export_zonefile ~154 tokens
  The whole zone as a plain-text BIND-format zonefile (all RRsets except DNSSEC types). Handy as a backup before changing records. Counts as an expensive deSEC operation (300/min). GET /domains/{name}/zonefile/.
• desec_get_domain ~145 tokens
  One domain with its DNSSEC key material: the DNSKEY and the DS records to publish at the registrar for the chain of trust, plus minimum TTL and publication times. GET /domains/{name}/.
• desec_get_rrset ~227 tokens
  One RRset by subname and type, e.g. the A records of "www" or the MX records of the apex. GET /domains/{name}/rrsets/{subname}/{type}/.
• desec_list_domains ~230 tokens
  List the DNS domains (zones) in this deSEC account, newest first, with creation and last-published times and minimum TTL. DNSSEC keys are omitted here (see desec_get_domain). Use owns_qname to find which of your domains is responsible for a DNS name (for example before adding a record for www.dev.ex
• desec_list_rrsets ~262 tokens
  List the DNS records of a domain as RRsets (all records of one name and type, sharing one TTL), newest first. Filter by type and/or subname. Up to 500 per page. GET /domains/{name}/rrsets/.
• desec_replace_rrset ~541 tokens
  WRITE (overwrites): set ONE RRset to exactly the given TTL and records, creating it if it does not exist and REPLACING all its current records if it does. It goes live in DNS immediately; a wrong value can take a site or mail offline. The previous RRset is read first and returned as `previous` so th
