Wildcard DNS A record not accepted

    Hi,

    Many of our domains have a plain * set for the host A domain record. This works great since the host and any subdomain get the target IP returned.

    At some stage the behaviour of the IPSConfig DNS parser has changed. When you enter * it is parsed to *.domain.tld and BIND9 will not resolve domain.tld. I suppose I could edit the record in phpMyAdmin and re-sync but that's not an option for users without Admin access.

    Is this intentional? Is there anyway other way to circumvent it?
    (Apologies if it has been answered but I couldn't find it)

    [ISPConfig 3.2.5, Debian 10 Perfect Server setup]

    '*' is valid in bind config, and will match any hostname which doesn't otherwise have any records, it will not match the domain itself, for that just leave the hostname blank (or try '@', which may or may not work).

    Hi Jesse, is that a default configuration? The * I mean.

    Is that the reason sites that hostnames with no dns record default to the first vhost? I don't like that behaviour So I am thinking I might have to change it if it is. That or I am setting up a new 000 vhost just to handle it.

    No. It is because of Apache, it chooses the first vhost in alphabetical order. Maybe nginx does the same?

    Okay, so then the better solution to prevent showing the first site for everything would be to create a default site that will be first alphabetically?

    I just don't like that one of my websites shows up whenever a host has no dns record I can just about handle the default apache page loading up, at least that's obvious what happened, it messed with me for a while until I realised what was happening.

    It's actually the other way, it happens when a domain does have dns setup, pointing to your server, but there is not a website configure for them (or configure incorrectly).

    Okay, yes that makes sense. so I just need to make if a record is there it either has a site or is removed.
