"What's the Best Way to Block an IP Address from Accessing My Network?"
Hey folks,
So I’ve been getting some sketchy traffic hitting my network lately, and I wanna block IP address of the offenders. Problem is, I’m not totally sure how to do it *properly*.
I’ve tried messing with my router settings, but tbh, it’s kinda confusing. Do I just add the IP to a deny list? Or is there more to it?
Also, does blocking IP address actually stop all traffic from that source, or can they just switch IPs and come back?
Would love some tips from anyone who’s dealt with this before. Like, step-by-step would be awesome.
Thanks in advance!
(PS: If there’s a better way than router settings, lmk!)
Hey! Blocking an IP address is a solid first step, but yeah, they can just switch IPs if they're determined.
For your router, most models have a "Firewall" or "Access Control" section where you can add IPs to a deny list. Check your router's manual—some brands like Netgear or TP-Link make it pretty straightforward.
If you wanna go deeper, look into tools like fail2ban (for servers) or Pi-hole (for network-wide blocking). They auto-block IPs based on rules.
Also, consider using Cloudflare if you're hosting anything—their free tier has IP blocking features.
Hope that helps!
yo, blocking an IP address is easy but kinda temporary. most sketchy traffic comes from bots that rotate IPs like crazy.
go into your router settings (usually 192.168.1.1), find the firewall section, and add the IP to the block list. but tbh, this is whack-a-mole.
better idea? set up a firewall like pfSense or OPNsense. way more control. or use a VPN to hide your network entirely.
if you're lazy, just enable "stealth mode" or whatever your router calls it. stops random scans at least.
Blocking an IP address is a band-aid fix, but here's how:
1. Log into your router (google "[your router model] admin access").
2. Look for "Security" or "Firewall" tabs.
3. Add the IP to the "Deny" list.
But like others said, they can just get a new IP. For long-term fixes, try:
- IPBan (free tool for automatic blocking)
- Windows Firewall (if it's just your PC)
- Changing your router's default port (stops script kiddies).
Also, check your logs to see if it's the same IP or random ones.
If you're dealing with persistent attacks, just blocking an IP address won't cut it.
Look into geoblocking—some routers let you block entire countries. Also, enable MAC filtering so only known devices can connect.
For advanced users, iptables (Linux) or Windows Defender Firewall can block IPs more granularly.
Pro tip: If it's a web server, use .htaccess to block IPs at the site level.
lol i feel you—router settings are a maze.
to block an IP address, it's usually under "Parental Controls" or "Access Restrictions" (yes, weird place).
but honestly, if it's a home network, just reboot your router. sometimes the sketchy IPs are just bots that move on.
if they keep coming, maybe your network's exposed? check Shodan to see if your IP is listed (scary but useful).
Blocking an IP address is like locking your front door—it keeps out casual intruders but not pros.
For routers:
- Find "Firewall Rules" or "Access Control."
- Add the IP to "Blocked Addresses."
But if it's a server, use CSF (ConfigServer Firewall)—it's got auto-ban features.
Also, change your router's admin password if you haven't. Default logins are low-hanging fruit for attackers.
Hey OP,
Thanks for all the tips! I tried blocking the IP address in my router's firewall (took some digging, but found it).
Quick question though—if I use something like Pi-hole, will it block IPs *before* they hit my router? Or is it just for DNS stuff?
Also, gonna check out Cloudflare like someone suggested. Appreciate the help!
(Update: The sketchy traffic dropped after blocking, but I’m still paranoid lol.)
