Comodo Internet Security caught my speedfan program trying to connect to 178.255.87.3 from local port 1687 to remote port 443. Is this legit? I have been using SpeedFan 4.49 for quite a while, 100% of the time to monitor my CPU and GPU temperatures and provide warnings if they are in danger of damage. But I am worried about security 178.255.87.3 is registered in the RIPE internet number authority as CCANet-Bradford in country GB. I know speedfan has the ability to do internet communication with a repository of information about overclocking. However I can't be sure that this site is legit. It is suspect because I did not initiate the connection, it connected on its own shortly after startup and it doesn't normally do so every startup, it is unusual. It is also suspect because the address seems not to be related to the speedfan website. A third factor is that i tested 178.255.87.3 in a web browser (Chrome) and it doesn't have a page. In other words http://178.255.87.3/ doesn't load a web page that might perhaps identify what the site is for. https://178.255.87.3/ tries to download a file but then reports "failure - no file"

DNSBL* - is a list of IP addresses published through the Internet Domain Name Service (DNS) either as a zone file that can be used by DNS server software, or as a live DNS zone that can be queried in real-time. DNSBLs are most often used to publish the addresses of computers or networks linked to spamming; most mail server software can be configured to reject or flag messages which have been sent from a site listed on one or more such lists.
WHOIS** - is a query/response protocol that is widely used for querying databases in order to determine the registrant or assignee of Internet resources, such as a domain name, an IP address block, or an autonomous system number. WHOIS lookups were traditionally performed with a command line interface application, and network administrators predominantly still use this method, but many simplified web-based tools exist. WHOIS services are typically communicated using the Transmission Control Protocol (TCP). Servers listen to requests on the well-known port number 43.
** Approximate Geographic Location - This is NOT the exact geographical location of the person/organization with the given IP address. However, this should still give you a good idea about the area/region where this person/orgranization is located.
