Do you use ANAME record?
What is ANAME record? ANAME record (also known as A record) is an alias record that allows you to map the apex record or any other record within your domain to a target host name, essentially a CNAME record for the apex record. ANAME record is especially useful for when you have multiple domain names and your website is hosted by a provider that changes it's IP Address, this does happen quite regularly with WPEngine. Many DNS service provider does not support ANAME record, however, DNSMadeEasy has made this service available.
Configuring ANAME is as easy as configuring CNAME. Let's have a look at DNS records for adamcogan.com.au, DNS records contains apex record for adamcogan.com.au and a www.adamcogan.com.au . The apex record uses ANAME, while CNAME for www.adamcogan. au - now we will never have to worry about updating these records, they will follow the DNS records of adamcogan.com .
