I was sure this has been already posted on my blog, but I guess I was wrong (or was it my old blog). Anyway, here they are, listed again. Most widely known and used DNS servers that can be used as alternative to the DNS servers provided by your ISP. In general, most users don’t really need to use these, but those who want extra security in a form of blocking websites that are serving malware or host phishing sites along with DNS poisoning defense, these alternative DNS servers can be useful. Some (like Norton ConnectSafe also offer blocking of porn, but you have to visit their webpage for those IP addresses, I’m only listing the antimalware/antiphishing one). Instructions to use each are also provided on their webpages if you don’t know how to set them up.
