you on shared hosting? people share ip's if neighbor malicious or things email spamming ruined reputation ip , in series of database project honeypot, cloudflare, , various others.

you can use services cloudflare go behind proxy , screen out malicious users, bots, etc. or query ip's against services reduce fraud , etc. shaw thinks it's spam based on behavior of ip in past.

we host joomla sites , use vps user's have dedicated resources , ip addresses. we've dealt businesses , result want security, piece of mind, performance, , etc. shared never option. should able dedicated ip on shared, few bucks extra.

or check out, can help, host, , migrate on .
