Network configuration
This.page.allows.you.to.configure.the.various.aspects.of.the.IP.port.and.its.
relationship.with.the.local.network.
MAC address
Media.Access.Control.address.–.this.is.the.unique.and.unchangeable.code.
that.was.hard.coded.within.your.AdderView.CATx.IP.unit.when.it.was.built..It.
consists.of.six.2-digit.hexadecimal.(base.16).numbers.separated.by.colons..A.
section.of.the.MAC.address.identifies.the.manufacturer,.while.the.remainder.is.
effectively.the.unique.electronic.serial.number.of.your.particular.unit...
Use DHCP
DHCP.is.an.acronym.for.‘Dynamic.Host.Configuration.Protocol’..Its.function.is.
particularly.useful.when.connecting.to.medium.size.or.larger.networks,.such.as.
the.Internet..When.this.option.is.selected,.your.AdderView.CATx.IP.will.attempt.
to.locate.a.DHCP.server.on.the.network..If.such.a.server.is.located,.it.will.supply.
three.things.to.the.AdderView.CATx.IP:.an.IP.address,.an.IP.network.mask.
(also.known.as.a.Subnet.mask).and.a.Gateway.address..These.are.not.usually.
granted.permanently,.but.on.a.‘lease’.basis.for.a.fixed.amount.of.time.or.for.as.
long.as.the.AdderView.CATx.IP.remains.connected.and.switched.on..

allocations .
IP Address
This.is.the.identity.of.the.AdderView.CATx.IP.within.a.network..The.
IP address .
can.be.thought.of.as.the.telephone.number.of.the.AdderView.CATx.IP..Unlike.
the.MAC.address,.the.IP.address.can.be.altered.to.suit.the.network.to.which.it.is.
connected..It.can.either.be.entered.manually.or.configured.automatically.using.
the.DHCP.option..When.the.DHCP.option.is.enabled,.this.entry.is.greyed.out.
IP Network Mask
Also.often.called.the.
subnet-mask ,.this.value.is.used.alongside.the.IP.address.
to.help.define.a.smaller.collection.(or.subnet).of.devices.on.a.network..In.this.
way.a.distinction.is.made.between.locally.connected.devices.and.ones.that.are.
reachable.elsewhere,.such.as.on.the.wider.Internet..This.process.helps.to.reduce.
overall.traffic.on.the.network.and.hence.speed.up.connections.in.general.
IP Gateway
This.is.the.address.of.the.device.that.links.the.local.network.(to.which.the.
AdderView.CATx.IP.is.connected).to.another.network.such.as.the.wider.Internet..
Usually.the.actual.gateway.is.a.network.switch.or.router.and.it.will.be.used.
whenever.a.required.address.lies.outside.the.current.network...
VNC Port
This.is.the.logical.link.through.which.communications.with.a.remote.VNC.viewer.
will.be.channelled.(see.
What is a port? )..The.default.setting.is.5900.which.is.
a.widely.recognised.port.number.for.use.by.VNC.software..However,.in.certain.
circumstances.it.may.be.advantageous.to.alter.this.number.-.see.‘Security.issues.
with.ports’.for.more.details...
HTTP Port
This.is.the.logical.link.through.which.communications.with.a.remote.web.
browser.will.be.channelled.(see.
What is a port? )..The.default.setting.of.80.is.an.
established.standard.for.web.(HTTP.–.HyperText.Transfer.Protocol).traffic.though.
this.can.be.changed.to.suit.your.local.network.requirements.
IP Access Control
This.section.allows.you.to.optionally.specify.ranges.of.addresses.which.will.
or.won’t.be.granted.access.to.the.AdderView.CATx.IP..If.this.option.is.left.
unchanged,.then.the.default.entry.of.‘+0.0.0.0/0.0.0.0’.ensures.that.access.from.
all.IP.addresses.will.be.permitted..See.
Setting IP access control .for.details..
