Hi Hugo, thanks for the help with this... I think I understand you to have recommended that I change the '1' to '120' in the last line of the reverse DNS zones file, as appended. This makes sense, but only after the fact! Cheers, Max $TTL 1d ; $ORIGIN 195.13.212.IN-ADDR.ARPA. @ IN SOA ns.exoco.net. admin.exoco.net.

Hi Andy, whatever you can do to reduce my need to set up config files for things of which I know little and care to understand less (ie reverse DNS, MX, network config) would be much appreciated. You should have received an email of request for reverse DNS, as I do not expect to change the domain name at all. If you tell me that, as a result of the support email, I no longer need to set a reverse DNS zones/master file I will remove it. Cheers, Max ________________________________ From: Andy Smith <andy(a)bitfolk.com> To: users(a)lists.bitfolk.com Sent: Mon, October 4, 2010 1:13:00 PM Subject: Re: [bitfolk] reverse DNS zone file Hi Max, Normally BitFolk does the reverse DNS for you. They're our IP addresses. Since there is only one entry, if you don't expect it to change much, just send a support request to support(a)bitfolk.com and we'll change it to whatever you like (it was set to what you asked for as a hostname when your VPS was set up). If you like we can also delegate the reverse DNS to your nameserver(s), which is the only time you would need a reverse zone as a BitFolk customer. Again if you want to do that, drop an email to support.

This is a complicated subject and requires a pretty good understanding of normal DNS before you can go the extra step to understand how doing reverse DNS for less than a /24 works. This technique is described in RFC2317: http://www.faqs.org/rfcs/rfc2317.html If you would like your reverse DNS to work even when ns.exoco.net is down then it would be advisable to have more than one nameserver. Since the only reverse DNS entry you have is *for* ns.exoco.net then it could be argued that more nameservers are pointless and that's fair enough. On the other hand since you definitely need more nameservers for other kinds of zones, you might view it as a good idea to standardise and put the same set in the reverse zones too. If you want more nameservers, BitFolk provides free secondary DNS for customers, for up to 50 domains: http://bitfolk.com/secondary_dns.html Again, if you are wanting your nameserver to receive queries for the reverse zone then you will need to contact support so that we can delegate it to you.
