18.104.22.168 PTR eglide.org
On the DNS server eglide.org is currently managed
eglide.org A 22.214.171.124
www.eglide.org A 126.96.36.199
We could also consider *.eglide.org A 188.8.131.52. That would allow to serve /home/quux/public_html to quux.eglide.org, in addition to eglide.org/~quux.
We then should mirror these A records to AAAA records to some IPv6.
No MX is especially necessary, as default configuration is to follow regular the regular A record.
