I checked my raw access files after being notified that my site has been limited over the last 24 hours and see different IP addresses trying to access files with .aspx extensions, see attached log image.

What are they trying to do and how can they be coming in every millisecond or so from different IP addresses?



I thought I'd update my question because this continues to happen and for the first time a request with no IP Address - see third log entry

You're either under attack (DDoS) or you're very popular and this is legitimate traffic (however, considering '403' the last is unlikely). And yes, if you've received this IP only recently then the requests are legitimate traffic to the previous owner of your IP.

There are quite a few ways to protect, and the most effective of them is a third-party CDN with such option. To name a few: CloudFlare, MaxCDN, Anazon CloudFront. Even without DDoS-protection CDN should be effective because it should cache '403' Unsure but it can have better effect if you respond with 404 instead of 403.
