Setup DHCP range

I'm about to do a full factory reset on my RAX80 and I'd like to reserve a range for assigned IP. What is best, to start the DHCP past the reserved range or have it at the beginning?

For clarification...

Say, start the DCHP at 100-254 and use the IPs below 100 to assign to various devices I wish to have static IP for.

 

Thank you in advance for any suggestions, along w/any OTHER recommendations in this process. I don't want to EVER do this again and I want more stability. (I know, wishful thinking, LOL)

Re: Setup DHCP range

I have mine setup with the DHCP scope set below 100 and the reserved scope starts at 101.  It works for me but that is just my preference.

   Define "best".  What difference would it make?

   So long as the ".100" - ".254" range is big enough for your DHCP-pool
needs, and the ".2" - ".99" range is big enough for your non-pool
needs, that should work.  (What could go wrong?)

   Putting the dividing line among the ".1xx" values is not the way I'd
do it.  As proposed above, _all_ ".1xx" and ".2xx" values are in the
same category.  No need for thought.  And, in the words of the
philosopher Williams, "If you don't think too good, don't think too
much."

Re: Setup DHCP range

Well folks!
The reason I ask, is because last week or so, I read a post saying that having the assigned IP area at the start (.1-.99) then then the DHCP pool. They talked about how the router starts looking to assign IPS, I don’t recall details & I wish I would’ve kept it.
Thank you all for your input! Tomorrow I’ll do it & see what color smoke I get. (Only OLD engineers like me would understand that. )

Antinode, I don’t understand your statement…

“ Putting the dividing line among the ".1xx" values is not the way I'd
do it. As proposed above, _all_ ".1xx" and ".2xx" values are in the
same category.” As I see it, it’s same as you already accepted as ok.

      https://en.wikipedia.org/wiki/Internet_Protocol
      https://en.wikipedia.org/wiki/IP_address

 

   ".1" is normally occupied by the router, so you'd use ".2" - ".99".
But which comes first between pool and non-pool makes no never-mind.
The DHCP server knows where the pool is, and what it's already granted,
and the reservations, which is all it needs to know.

 

   No one (with a job) is stupid enough to scan through the ex-pool
addresses to find the start of the pool; the start of the pool is well
known.

 


> [...] I don't understand your statement... [...]

 

   Apparently, I misread "below 100" as "100 and below", as if ".100"
were the DHCP server Finish IP Address.

 

   But then "the reserved scope starts at 101" makes no sense.  If the
pool ends at ".99" ("below 100"), then the non-pool range starts at
".100", not ".101".  Sorry to add my confusion onto existing confusion.

 

   One reasonable goal is to make it easy to distinguish between in-pool
and ex-pool.  My (simple) point was that "If it looks like "1xx" or
"2xx", then it's <whatever>" is easy.  "If it's ".101" or above" is too
messy.

Re: Setup DHCP range

But it WOULD be ez, all two digit IPs are reserved, all three digit IPs are in the pool.

Re: Setup DHCP range

Sorry, not enough coffee yet lol

Perhaps you didn’t understand my response & I know my English is not the best.

.1 - .99 is the reserved pool
.100 - .254 is the DHCP pool.

BTW, I’ll be doing this in the next hour or so as of this writing.
Thanks to all!

   Nor you mine?

   Fine with me, but inconsistent with "the reserved scope starts at
101" (as stated by the other fellow).

Re: Setup DHCP range

Ohhh, you’re referring to the other guy, ok.
And yes, of course .1 is the router itself, that goes without saying, just didn’t want to be THAT specific.

Re: Setup DHCP range

Well, just done it, still setting it up and I'm already getting mad (putting it politely)!

The reason for this exercise was at the request of the tech support for Circle, it says RAX80 is not supported.

Well, so much for that crap, especially since it originaly WAS, and I purchased it shortly after I purchased the RAX80.

In fact, it's still promoted when  you first setup the router and asks you to setup it.

 

I'm not too  mad, since I WAS planning on doing this since it's been flaking out for a while now. Hopefully this fixes it.
