If you manage a website, run servers, monitor firewalls, or work in cybersecurity, the term 24.14-12.16 has probably popped up in your logs more than once. At first glance it looks strange, almost like a secret code or a measurement for a drum kit. Relax – it’s nothing mysterious at all.
24.14-12.16 is simply a shorthand way that network professionals use to refer to a small slice of Internet Protocol (IP) addresses that belong to Comcast Cable Communications in the United States. Specifically, it covers addresses roughly from 24.14.12.0 all the way through 24.14.16.255 – a perfectly normal group of home and small-business internet connections around the Chicago area in Illinois.
Every device that connects to the internet needs a unique number so computers can find each other. These numbers are called IPv4 addresses, and they are handed out in big blocks to internet service providers (ISPs) like Comcast, AT&T, Verizon, and Spectrum. The entire 24.14 IP address range (from 24.14.0.0 to 24.14.255.255) is one of those big blocks owned by Comcast.

Is 24.14-12.16 Dangerous or “Blacklisted”?
No – not as a whole range.
Just like any large ISP, a tiny percentage of Comcast customers might run malware, try to brute-force passwords, or send spam. Security companies sometimes flag individual IPs inside 24.14-12.16, but the entire range is perfectly legitimate.
Best practice: Block only the single IP that misbehaves, never the whole 24.14 IP address range. Blocking thousands of innocent Chicago-area customers would hurt your business.
