How to Block Servermania – B2 Net Solutions CIDR and ASN

ByTycho Brahe

Updated: August 2023

1/5 of our traffic in a travel site comes from Servemania/B2 Net Solutions attacks against our WordPress. Use the following information to block their IPs and ASN. It is much better to block by ASN, still not an easy option for most webmasters.

Use your .htaccess file, Cpanel IP Blocker, your Wordpess security plugin, Cloudflare or whatever other method may you have:

ASN55286
ASN55081
ASN56030
CIDR154.30.215.0/24
CIDR38.154.0.0/24
CIDR23.229.13.0/24
CIDR38.15.136.0/21

Use ONE method to block them, via ASN or via CIDR, not both. Some of the CIDR belong/point to 24shells or Colocrossing or BlazingSEO, still they are related or managed to Servemania/B2 Net Solutions in Canada.

  1. Servermania seems to have a serious SPAM problem, they have many ‘commercial bulk email marketer’ clients, aka spammers, who cross post email addresses across client lists in violation of current SPAM laws. Further, Servermania seems to intentionally disregard abuse reports sent to abuse@servermania, postmaster@servermania, noc@servermania, support@b2netsolutions. 43 Spamcop reports in the last 12 days, 3 emails per report, and 20 personalized reports to abuse@servermania.com from the affected email address. No response whatsoever from Servermania or B2NetSolutions and no abatement in the SPAM sent from their network. These folks are unable or unwilling to address their customers violating their own Terms of Service and refuse to even reply to 149 emails asking them to address the issue. Support in a timely fashion from Servermania seems impossible.
