Traffic from AS174 comes from Cogent's network. Transit networks carry other networks' traffic, so the address you see may belong to one of their customers: look up the IP itself for its origin network.
whois AS174 shows the registry record, including the abuse contact. The abuse report generator turns your logs into a report the network can act on.
Questions
Who owns AS174?
Cogent. Press Look Up above for the current registry record.
How do I report abuse from AS174?
Find the abuse contact with whois on the offending IP (the abuse-mailbox or OrgAbuseEmail field) and send a report with the source IP, times in UTC and log lines.
How do I block traffic from an ASN?
Get the ASN's announced prefixes (for example from bgp.tools or whois -h whois.radb.net -- '-i origin AS174') and add them to a firewall set. Prefixes change, so refresh the list regularly.
