About .ac.lk
.ac.lk is a multi-level public suffix sitting one level below .lk. Suffixes like this exist because registries reserve a second level for specific registrant categories. Registrants treat them as if they were top-level TLDs, and so do webatla datasets.

The .ac.lk dataset
Everything we have on 107 .ac.lk domains in one downloadable file — fresh export every day. Same columns and cadence as any top-level TLD.
Buy a dataset to download .ac.lk
The full .ac.lk slice (548 B JSONL, fresh daily exports) lives inside each dataset. Get one from €29 to €599 per month and download immediately.
How to download the .ac.lk domain list
The complete .ac.lk domain list is available as one structured file. Every entry in the list is a single registered domain exported with its full record, so you can work it all offline instead of crawling it yourself.
Pick the dataset that fits your use case, then download the .ac.lk list in JSONL (zstd-compressed) — the very same list that powers our API. A free sample of the list is available before you pay, and you can re-download the latest export any time during your access month.
Each .ac.lk list includes, for every domain:
- DNS, RDAP and WHOIS records — registrar and dates across the full list.
- Detected technologies for each site in the list.
- Hosting IP, country and PageRank / Harmonic ranking.
- A daily-refreshed export, so the list you receive is never stale.
