SoftBank IP Ranges
SoftBank's Japanese consumer network is registered as AS17676 under the AS name GIGAINFRA. Its reverse DNS is one of the most literal in this section: the hostname is the word softbank followed by the address, each octet padded to three digits.

What does a SoftBank IP mean in a privacy test?
A SoftBank address as your visible IP means the connection left over the Japanese line itself with nothing tunnelling it. The hostname is worth reading before anything else, because it names the operator and repeats the address, which together rule out the two things a leak test is usually trying to exclude - a proxy and a mismatched lookup.
Where to get SoftBank's address list
SoftBank publishes no allowlist, so the registry is the source - and the registry for this network is not quite where you would expect. Japanese number resources are administered by JPNIC as a national registry under APNIC, so an APNIC RDAP query for AS17676 redirects to JPNIC's own service before it answers. What it returns is the AS name GIGAINFRA and the organisation SoftBank Corp. in Japan, with the object last changed in June 2023. The AS17676 page carries the record with the routing detail.
The announcement list is short for a network this size: a few hundred IPv4 prefixes, and the largest of them are very large - 60.64.0.0/10, 60.128.0.0/11, 219.32.0.0/11 and 221.64.0.0/11 between them cover an enormous amount of the consumer base. That makes SoftBank one of the few consumer carriers where a handful of aggregates genuinely does most of the recognising, though the ASN remains the key that keeps working when the aggregates change.
The hostname spells the address out
60.64.1.1 answers as softbank060064001001.bbtec.net. Read it in groups of three: 060, 064, 001, 001 - the four octets, each padded to three digits, after the operator's own name. The zone is bbtec.net, from BB Technology, the broadband business SoftBank built its consumer network on. A name in that form is self-checking, because decoding it has to give back the address you looked up, and it identifies the far end as a SoftBank subscriber line rather than a hosted machine.
What it settles and what it does not are both worth stating. It settles that the address is consumer access on AS17676, which is not space anybody rents by the hour, so it is a poor candidate for a proxy or a VPN exit. It does not place the line - there is no city or prefecture in the name, unlike Bell's or Telstra's - and it does not identify a subscriber, because nothing published maps these addresses to accounts.

Frequently asked questions
What IP ranges does SoftBank use?
SoftBank announces its Japanese consumer network under AS17676, registered to SoftBank Corp. under the AS name GIGAINFRA. The largest blocks currently routed there are listed above, among them 60.64.0.0/10, 60.128.0.0/11 and 219.32.0.0/11. No allowlist is published, so the registry and the routing table are the sources.
Why does a SoftBank IP appear in my privacy test?
A SoftBank address as your visible IP means the connection left over the Japanese line itself with nothing tunnelling it. The hostname is worth reading before anything else, because it names the operator and repeats the address, which together rule out the two things a leak test is usually trying to exclude - a proxy and a mismatched lookup.
What does softbank060064001001.bbtec.net mean?
It is the address written out. Read the digits in groups of three - 060, 064, 001, 001 - and they are the four octets of 60.64.1.1, padded, after the operator's name. bbtec.net is the zone, from BB Technology, the broadband business SoftBank's consumer network was built on.
Which registry holds SoftBank's records?
JPNIC, acting as a national registry under APNIC. An APNIC RDAP query for AS17676 redirects to JPNIC's own service before it answers, which is normal for Japanese number resources and not a sign that anything is wrong with the lookup.
Can a VPN exit run on a SoftBank address?
It would be unusual. AS17676 is consumer access sold to subscribers rather than compute rented by the hour, so there is no third-party machine on this space to host one, and the reverse DNS names every address as a SoftBank line.
