    Try creating an A record www.testsite2.mycompany.local on your DNS server.

    No Problem...

    its easy..

    edit LMHOSTS.SAM file.. you can find it in same folder with hosts, at "C:\Windows\System32\drivers\etc"

    kindly add two lines as given below

    127.0.0.1 testsite1.mycompany.local
    127.0.0.1 testsite2.mycompany.local
    ...
    For doing this you need to open notepad with administative priviledge
    hope you can do it.
    please do not hasitate to write at Q&A, here, if any query
    good luck

    You should probably use cname records for host header names, especially if use DHCP

    Hi @AJF ,

    The only ways for a computer to know the mapping between a domain name and an IP address are DNS or local hosts file. So if you don't want to edit hosts file, edit DNS is more suitable for you.

    If you have owned DNS, you can add a record to map root domain to IP. Just click IPAM in Server Manager and navigate to MONITOR AND MANAGE, click DNS Zones and Forward Lookup, then you can add a DNS record. More steps can refer to this docs.

    Otherwise, please contact your DNS provider to set record for you.

    As for CNAME, I personally recommend it for setting up subdomain mappings. Map subdomains to hostnames instead of specific IP addresses. You can get reasons from this docs.

    There are actually two other alternatives, a WINS server and the LMHOSTS.SAM file.
    Windows used the WINS server long ago when DNS was not in use and it still works today. But you need to prepare a separate Windows server for this.
    The LMHOSTS.SAM file works like the HOSTS file, but with a different syntax; it's also located in the same place: C:\Windows\System32\drivers\etc.
