Subdomain wildcards?

Post by alex.barylski »

Quick question: We have asked our ISP to use a wildcard for our domain, but how many sub-domains can we actually use, for instance, we would like to have our sub-domains map to city/states of customers, something like:

Code: Select all

city.state.domain.com
Possible? Any special requests or requirements outside a wildcard domain?

What do you mean by "wildcard" - especially where it concerns your ISP? The only place I've heard that term used is when it concerns security certificates. In that case, the number of sub-domains is infinite.
Real programmers don't comment their code. If it was hard to write, it should be hard to understand.

From Wikipedia, the free encyclopedia
A wildcard DNS record is a record in a DNS zone that will match requests for non-existent domain names. A wildcard DNS record is specified by using a "*" as the left most label (part) of a domain name, e.g. *.example.com.

It's certainly possible, no really special requirements

OK cool. So you could have multiple sub-domains, virtually unlimited, so long as the length of the domain namespace didn't exceed 255 characters or whatever? :D
