About this network

JANIS is operated by Naganoken Kyodou Densan Co.Ltd.

What it's used for

• The address space carries residential and small business internet access, evidenced by the reverse DNS record janis220254191254.janis.or.jp and the netname JANIS-CIDR-BLK-JP.
• The AS announces 67,072 IPv4 addresses across 3 prefixes and 1 IPv6 prefix, while maintaining 18 observed neighbours; this ratio of address volume to peering partners indicates a regional access provider rather than a transit carrier.

Notable

• All three IPv4 prefixes are registered to the Japan Network Information Center (JPNIC) under the netname JANIS-CIDR-BLK-JP, which aligns with the AS holder's identity as a Japanese regional ISP.
• The inventory consists of one large /16 block (220.254.0.0/16) and two smaller blocks (202.233.80.0/22 and 103.142.6.0/23), reflecting a consolidated regional footprint.
