6-Letter .io Domains That Are Still Available

6 letters is 308,915,776 possible .io names. The zone file lists 142,588 of them as registered, so about 308,773,188 are not — an estimate rather than a bound, since a zone misses a registration nobody pointed anywhere and keeps listing names that have since dropped. The names below are the exception: each was confirmed with a registrar.

Find your own

Nobody can search 308,915,776 names at once, and a tool that offered to would be lying — the largest plan here checks 10,000 in a run. What works is taking a corner of the space at a time: fix the first 3 letters and cross them with every two-letter ending, which is 676 combinations and runs on a free account.

Change the opening to move somewhere else in the 308,915,776. Nothing runs until you click search.
