isp residential japan access

HAL-INTERNET is operated by HAL Internet, an internet service provider based in Tottori, Japan.

What it's used for

  • The address space carries residential broadband traffic, evidenced by the reverse DNS entry flets-4-254.hal.ne.jp which references FLET'S, a fiber-to-the-home service.
  • The AS announces a single IPv4 prefix of 202.180.56.0/21, totaling 2048 addresses, with no IPv6 prefixes in inventory.
  • With only one observed neighbour in RIS, the low neighbour count relative to the address block indicates this is an access or eyeball network rather than a transit provider.

Notable

  • The RDAP registrant for the announced prefix is listed as Japan Network Information Center (JPNIC) with netname HAL-NET, which is consistent with JPNIC managing the allocation for the Japanese ISP.
  • The address inventory consists of a single contiguous /21 block, representing a standard-sized allocation for a regional ISP.

Classification and threat

Unclassified Not in the curated lists. Most of the ~80,000 allocated ASNs are not.

Spamhaus DROP

Not on ASN-DROP The network as a whole is not listed.

No DROP prefixes None of its announced space is on the DROP prefix list.

Spamhaus DROP ("Don't Route Or Peer") lists space and networks run by, or hijacked for, spam and cybercrime operations: 442 networks and 1,773 prefixes, as published 2026-10-13. A short, high-confidence list, so a match is worth taking seriously, and absence from it says little on its own.

FBI IC3

No IC3 indicators Nothing from the FBI IC3 feed.

IC3 threat data is alpha. Absence of an indicator is not evidence of good behaviour, only of absence from this one feed.
