Add Multiple DNS Suffixes

mario11584 — Sat, 25 May 2013 17:53:13 GMT

Is there a way to add more than one DNS suffix to DHCP?

I know in Mac OS X I can add multiple search domains, but I don't want each user to have to do this, nor type in our long domain names each time either.

Thanks!

I tested this, and yes, you can add more than one.

It will not work if you use commas as delimiters, you need to separate the entered suffixes with spaces.

Sure thing. This is under Network > DHCP > DHCP Server. Here's a screenshot where I have adomain.local, and additionally otherdomain.local in the DNS Suffix list. Using a space will create multiple Search Domains on the computers.

Example. If I tried to resolve with nslookup (or anything else that needs to resolve the name) like:

nslookup hello

My computer will ask my DNS server for:

hello.adomain.local

hello.otherdomain.local

If instead of using a space in between adomain.local and otherdomain.local, you used a comma, it will be asking for:

hello.adomain.local,otherdomain.local

... so it gets confused with commas and concatenates the suffixes. It works fine if you separate them with a space.

I'll write a KB with further details and publish it on live...

Best,

This solution was superseded by the ability to set DHCP Options. See article: https://knowledgebase.paloaltonetworks.com/KCSArticleDetail?id=kA14u000000saawCAA
