## About

NetLoom is the subnet tool for when you have a whole list, not one address. Paste a column of addresses, CIDR blocks and start-to-end ranges, and every line comes back parsed, classified and ready to export.

— WHAT MAKES NETLOOM DIFFERENT —
• Paste a list, read a list
  The Batch tab takes multi-line text and works out, for each line, whether it is an address, a CIDR block, a range or invalid.
• Ranges reduced to the fewest CIDR blocks
  Give it a start and an end address and NetLoom returns the minimal set of CIDR blocks covering exactly that span, nothing more and nothing less.
• Every address placed on the IANA map
  Public, private, loopback, link-local, multicast, carrier-grade NAT, documentation, reserved, broadcast or unspecified — ten categories, each named.
• CSV out
  Batch results export as CSV, so the answer goes straight into the sheet or the ticket it was needed for.
• IPv4 and IPv6, offline
  Dotted, compressed, hexadecimal, binary and 128-bit decimal forms, with no network call at any point.

— PRICING —
Included: the single-address calculator, IANA classification, the opening rows of any batch, and five saved calculations.
NetLoom Pro is a one-time in-app purchase, never a subscription. It opens the full batch result, CSV export and unlimited history.

— FEEDBACK —
Made by a small indie team. Email obeliskclubclub@gmail.com with feedback, bug reports, or feature requests.
