Since you say it is legit I will add an exception to my security software not to block that ip.
I did say it
appears to be legit and I still think they are.
I wish AbuseIPDB defined what
specific "abusive activity" actually occurred. There are many legitimate reasons why "port scans" (the most often reported category) may occur. A port scan does NOT imply an "intrusion". Plus I note in that AbuseIPDB report, a couple of those were "outbound" attempts. That does not suggest anything (good or bad) towards Swiftway. If anything, it suggests something (good or bad) has already been let through to the client system that is now attempting to "call home".
I have my router send me a copy of its logs every day and I regularly see scary entries like DoS attack: ACK Scan, DoS attack: FIN Scan, DoS attack: Smurf Scan, and LAN access from remote. Most are from Akamai Technologies, Netflix (I am a subscriber), Cox (my ISP),
Google (AbuseIPDB), and even Amazon and
Microsoft (AbuseIPDB). Why? I don't know, but they do - yet I don't suspect malicious activity from them either, even when reported to AbuseIPDB.
But some have been from China Unicom, TurkTelecom, Montenegro Telecom and other entities I don't know and don't trust (and don't appear in AbuseIPDB, BTW). But the point is, while my router sees these attacks, it is not letting them through to my network. It is blocking them all. A good thing, for sure.
Just today, my router was hit by Amazon, Cox and a new site,
Internap. I don't know who Internap is but
AbuseIPDP shows DoS attack: ACK Scans from them too, just like Microsoft and Google. But again, my router blocked them BEFORE they were able to reach any of my connected computers. A very good thing.
I see even
AbuseIPDB has been reported for "abusive activity". :r1:
I don't think it would hurt to contact Swiftway.net and hear what they have to say and note if the hairs on the back of you neck stand up, or not. But again, from what I can see, they
appear to be legit.
