IPChains hostname has multiple IPs is resolves to?

I want to block the hostname (don't we all). I've attempted to put in a clause in my firewall script as such:

ipchains -A input -b -i eth0 -p tcp -s -d $MYIP -j REJECT

but it doesn't seam to work.
I'm ipchains unable to work with hostnames that resolve to multiple IP addresses?

ipchains will block whichever IP resolves to when the rule is inserted. It won't re-evaluate the IP until the rule is flushed and reloaded.

You'll need to block all the IPs associated with the A record. Better still you could use squid and squidguard to block banners.
