One thing people might notice is that on the dhcp page (and updatexlrator page if a table is shown there), the tables that are shown do not have the alternate rows with different shadings effect. It is just one white table with no visible separation between the rows.
This is due to an error I made with a fix for a bug. A patch fixing this effect has already been submitted today and should be fed into CU174 in the next few days or so
The orange colour is if you have entered an IP for a fixed lease that is not within either the green subnet or the blue subnet.
The red colour is if you have entered an IP for a fixed lease that is within the dynamic range of IP’s that you have defined. Your fixed lease IP’s should always be outside the dynamic IP pool. This is mentioned in the wiki page on dhcp.
These are fixed leases with IP’s that are either in the green subnet range or in the blue subnet range. These generally should be all or the majority of any entries in this table.
The Orange colouring option has always been present for a long time. It is just that any fixed lease IP’s that are part of the overall network but not in the green or blue subnet are likely to be in the orange subnet. Historically an entry of that type would not have been shown in orange because of the use of bgcolor, which was deprecated in HTML4.01 and does not work with HTML5. In CU174 bgcolor was replaced in dhcp.cgi with its CSS equivalent.
If you have a fixed lease IP that is outside of the green or blue subnets then that entry should not be enabled because the dhcp server will not be able to access it but you could have it noted in the fixed leases table as a reminder.
It is also of use if you were intending to enter an IP within either the green or blue subnets but made a typo. The entry being flagged up in orange is telling you that the entry is outside of either the green or blue subnets.
The red flagging option is new in CU174.
If you have, for example, a dynamic ip range on green from 192.168.220.20 to 192.168.220.50 and you then define a fixed lease IP of 192.168.220.30, which is within the dynamic range, then it will be flagged up in red so that you are aware of it and can go and fix it.
If people have historically overlapped their fixed and dynamic leases then they might see many entries in red. They will still be able to use them but they should then over time correct that overlap situation to remove the red flagged entries.
