The COVID-19 stuff is keeping me a bit busy so I will just throw out the two biggest issues I came across:<\/p>\n\n\n\n<ol class=\"wp-block-list\"><li>You <a rel=\"noreferrer noopener\" href=\"https:\/\/docs.microsoft.com\/en-us\/azure\/dns\/dns-reverse-dns-for-azure-services#can-i-configure-reverse-dns-for-ipv6-publicipaddress-resources\" target=\"_blank\">cannot set a PTR for an IPv6 on Azure<\/a>! Your mail server would hate that&#8230;<\/li><li>They <a rel=\"noreferrer noopener\" href=\"https:\/\/docs.microsoft.com\/en-us\/azure\/virtual-network\/ipv6-overview#pricing\" target=\"_blank\">price IPv6 * per address * just like IPv4<\/a>. Wait&#8230; What ?<br>That&#8217;s right. Where most of the industry give you a \/64 for the price of a single IPv4 address Azure have the audacity to cheerfully announce that a single IPv6 address won&#8217;t cost you any extra: <\/li><\/ol>\n\n\n\n<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\"><p>IPv6 Azure resources and bandwidth are charged at the same rates as IPv4. There are no additional or different charges for IPv6.<\/p><\/blockquote>\n\n\n\n<p class=\"wp-block-paragraph\">Queue the abrupt showstopper record scratch sound effect&#8230;. <\/p>\n\n\n\n<figure class=\"wp-block-audio\"><audio controls src=\"https:\/\/7dc.org\/wp-content\/uploads\/2020\/04\/160907__raccoonanimator__cue-scratch.wav\"><\/audio><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">This is where my enthusiasm faded. Who hands out single IPv6 ? You can request a public IPv6 prefix but there they limit you to a \/124. <\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"818\" height=\"305\" src=\"https:\/\/7dc.org\/wp-content\/uploads\/2020\/04\/azure_prefix2.jpg\" alt=\"\" class=\"wp-image-237\" srcset=\"https:\/\/7dc.org\/wp-content\/uploads\/2020\/04\/azure_prefix2.jpg 818w, https:\/\/7dc.org\/wp-content\/uploads\/2020\/04\/azure_prefix2-300x112.jpg 300w, https:\/\/7dc.org\/wp-content\/uploads\/2020\/04\/azure_prefix2-768x286.jpg 768w\" sizes=\"auto, (max-width: 818px) 100vw, 818px\" \/><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">Many applications will need a \/64 or at least a \/112 prefix. OpenVPN server for example.
