The host 223.137.133.29/32 is associated with AS17421 (EMOME-NET), a routing operator in Taiwan. The address falls within the 223.136.0.0/15 CIDR block registered to the Mobile Business Group.

DNS hygiene assessment returned a score of 100 with a "Partial coverage" label; CAA records were present for hinet.net, but SPF and DMARC records were absent, and DNSSEC status was unknown. Network role analysis classifies the host as "Firewalled / No Services," indicating no active services were detected on the endpoint. TLS probes and endpoint enumerations yielded no results. The risk score is 0. While the absence of detected services suggests limited exposure, the lack of SPF and DMARC configurations prevents definitive validation of email authentication policies for this block. Continuous monitoring is recommended to detect any future service launches or policy changes.
