-H "Host:x.y.z" http://MyIP/ is not using the provided IP and is going through the DNS

Hi I am using Siege 4.0.5 on centos 7. when I issue: siege --delay=0 -p -t2S -c1 -H "Host:x.y.z" http://Server's-IP/ The request is still going through the DNS and hence cloudflare. The whole reason I am using the server's IP and the host-header is to circumvent cloudflare i.e., the siege --delay=0 -p -t2S -c1 -H "Host:x.y.z" http://Server's-IP/ is behaving as if I have typed: siege --delay=0 -p -t2S -c1 http://x.y.z/

I tried the same header with apachebench and it is working just fine (it is hitting the server via the specified IP address) and then branches tot he host (as expected).

Same problem here, even when I use an IP address it hammers the crap out of my DNS server. I tried putting a short hostname in the /etc/hosts file but it still insists on querying external DNS.
